Smart Water Leak Detection & Automatic Shut-Off System

Smart Water Leak Detection & Automatic Shut-Off System

Detect Slow Leaks. Stop Burst Hose Pipes. Save Water Automatically.

FlowShield is a smart water leak monitoring system that detects abnormal continuous water flow, slow leaks, burst hose pipes, and unattended taps — then automatically shuts off the water supply to help prevent water damage and water wastage.

Prevent Water Damage Before It Becomes Expensive

Water leaks can happen anytime — at night, during office closure, over the weekend, or while you are away on holiday.

A bidet hose may burst. A flexible pipe may fail. A water tap may be left slightly open. A valve may not be completely turned off. When nobody is around, water can continue flowing for hours or even days.

FlowShield is designed as a practical water leak detection system with automatic water shut-off. It helps protect homes, offices, rental units, toilets, pantries, shops, and facility zones from unnecessary water loss and water damage.

Common Water Leak Problems

Common Causes

  • Burst bidet hose
  • Water tap not fully turned off
  • Valve not completely closed
  • Toilet cistern leaking continuously
  • Faulty flush valve
  • Worn flexible hose
  • Loose pipe connection
  • Pantry tap left running
  • Washing machine hose failure
  • Water dispenser slow leak

Possible Damage

  • Unnecessary water wastage
  • Flooded toilets, kitchens, pantries, or service areas
  • Damaged cabinets, flooring, walls, and ceilings
  • Leakage to lower floors
  • Expensive repair work
  • Complaints from neighbours or tenants
  • Business interruption
  • Facility maintenance headaches

More Than a Basic Water Leak Alarm

A normal water leak alarm usually detects water only after it has reached the floor. By then, the water may already be spreading.

FlowShield works differently. It monitors the water supply line using a water flow sensor. When the system detects abnormal continuous water flow, it can trigger an alert and automatically close the shut-off valve.

If water keeps flowing continuously beyond the preset timing, FlowShield treats it as a possible leak, burst hose pipe, unattended tap, or faulty valve — and shuts off the water supply automatically.

Detects Slow Leaks and Burst Hose Pipes

Not all water leaks are the same. Some leaks happen suddenly with high water flow. Some leaks are small, slow, and easy to miss.

FlowShield can be configured to detect both fast leak events and slow continuous leak events by monitoring water flow rate and continuous flow duration.

Fast Leak Detection

High-flow leakage can waste a large amount of water quickly and cause serious damage.

  • Burst bidet hose
  • Broken pipe
  • Fully opened tap
  • Failed flexible hose
  • Pipe joint failure
  • Toilet hose bursting

Slow Leak Detection

Small continuous leaks may look harmless, but they can waste water for many hours if nobody notices.

  • Tap not fully turned off
  • Valve not completely closed
  • Toilet cistern slowly leaking
  • Flush valve not sealing properly
  • Bidet spray slightly dripping
  • Small pipe joint seepage
  • Water dispenser slow leak

How the Automatic Water Shut-Off System Works

1. Monitors Water Flow

A water flow sensor is installed on the water supply line to detect water movement through the pipe.

2. Measures Flow Duration

The electronic controller checks how long the water has been flowing continuously and compares it with the preset timing.

3. Detects Abnormal Usage

If the water keeps flowing for too long, the system identifies it as a possible leak, burst pipe, or unattended tap.

4. Closes the Water Valve

The automatic shut-off valve closes the water supply to stop further leakage and water wastage.

5. Sounds Alarm or Sends Alert

A local buzzer, LED indicator, or remote notification can alert the homeowner, office, or maintenance team.

6. Reset After Inspection

After the problem is checked and corrected, the user can press a reset button to restore normal operation.

Configurable Water Leak Monitoring

Every location has a different water usage pattern. FlowShield can be configured based on the expected usage of the area.

Area TypeExample Trigger SettingPurpose
Toilet Area10 minutesDetect unattended taps, burst bidet hoses, and abnormal toilet water usage
Home Use30 minutesGeneral protection against leaks, burst hoses, and forgotten taps
Pantry or Utility Area60 minutesAllow longer normal usage while still detecting abnormal continuous flow
Commercial or Facility AreaCustom timingAdjust based on site operation and water usage behaviour

For high-usage public areas, the system can also work with a human traffic sensor or occupancy sensor to help differentiate normal heavy usage from unattended water leakage.

Suitable for Homes, Offices, Rental Units and Facilities

FlowShield can be used as a home water leak detection system, an office water leak monitoring system, or a facility water leak prevention system.

Homes and Apartments

Protect against burst bidet hoses, leaking toilets, unattended taps, and water pipe failures while the family is asleep or away.

Small Offices

Monitor toilets, pantries, utility rooms, and cleaning points after office hours.

Rental Properties

Reduce the risk of unattended water damage caused by tenants, worn fittings, or forgotten taps.

Shops and Commercial Units

Protect premises during non-operating hours, weekends, and public holidays.

Schools, Hostels and Dormitories

Monitor washrooms, common toilets, pantries, and shared utility areas.

Factories and Warehouses

Deploy protection in selected water supply zones without shutting down water to the entire building.

Zone-Based Water Shut-Off Protection

For buildings and facilities, multiple FlowShield units can be installed strategically in different zones. This allows the system to isolate only the affected area instead of cutting off water to the entire building.

  • One unit for each toilet
  • One unit for each pantry
  • One unit for each rental room
  • One unit for each office floor
  • One unit for each building section
  • One unit for each high-risk water point

This makes FlowShield suitable for facility water leak monitoring, remote water leak alert, and selected-area automatic water shut-off applications.

Timer-Based Monitoring for Night, Weekend and Holiday Protection

Some locations have normal water usage during the day but very little usage at night. FlowShield can be configured to monitor more actively during selected periods.

  • Night monitoring from 10:00 pm to 7:00 am
  • After-office-hours monitoring
  • Weekend protection mode
  • Holiday protection mode
  • Special closure period monitoring

This is useful for homes, offices, shops, schools, dormitories, and facilities where water leakage may go unnoticed during non-operating hours.

Key Benefits of FlowShield

  • Automatic water shut-off when abnormal continuous flow is detected
  • Slow leak detection for taps, valves, cisterns, and small pipe seepage
  • Burst hose pipe protection for bidet hoses and flexible water hoses
  • Water damage prevention for homes, offices, and facilities
  • Remote water leak alert option for responsible personnel
  • Zone-based protection to isolate only the affected area

Flow-Based Detection vs Floor Leak Sensors

Floor leak sensors are useful, but they only detect water after it reaches the sensor location. If water flows in another direction, the leak may not be detected immediately.

FlowShield detects abnormal water usage from the water supply line itself. This helps identify possible leaks before water spreads across the floor.

This makes FlowShield especially useful for toilets, pantries, under-sink areas, concealed areas, service rooms, rental rooms, and unattended premises.

Example Scenario: Burst Bidet Hose at Night

A bidet hose bursts at 2:00 am. Without protection, water may continue flowing for hours until someone wakes up or returns to the premises.

  1. FlowShield detects continuous water flow
  2. The controller starts measuring the flow duration
  3. The flow continues beyond the preset timing
  4. The automatic water shut-off valve closes
  5. A local alarm sounds or remote notification is sent
  6. Water wastage and damage are reduced
  7. The user resets the system after inspection

Example Scenario: Tap or Valve Not Fully Turned Off

A tap or water valve is not completely closed after use. Only a small amount of water continues flowing, so nobody notices immediately.

Without monitoring, this small leak may continue overnight or during a long holiday period.

  1. FlowShield detects small continuous water flow
  2. The controller monitors the flow duration
  3. The system identifies abnormal long-duration water usage
  4. An alert or automatic shut-off is triggered
  5. Water wastage is stopped

Controller for Electrode Water Sensor Rods

Water Tank Level sensor controller

Choosing the Right Controller for PS-5R Water Level Sensor Rods

The PS-5R electrode holder is used together with a conductive / floatless water level controller. The electrode rods detect water contact, while the controller converts that signal into relay output for pump control, high level alarm, low level alarm, or level indication.

✓ Water tank level sensing

✓ Pump control

✓ High / low level alarm

✓ Conductive liquid sensing

PS-5R Is the Sensor Holder — The 61F Is the Controller

A common misunderstanding is to treat the PS-5R as a complete water level sensor system. In actual use, the PS-5R is the electrode holder and rod assembly. It needs a compatible controller such as the Omron 61F series to operate the relay output.

1. Electrode Holder

PS-5R

Holds up to 5 electrode rods. The rods are cut to different lengths according to the required water levels.

2. Controller

61F Series

Detects the conductive path through water and provides relay output for control, alarm, or indication.

3. Output Device

Pump / Alarm

The controller output can drive a contactor, pump starter, alarm lamp, buzzer, PLC input, or BMS input.

Most Common Controller Choices

For most PS-5R water level applications, customers usually choose between a basic controller such as 61F-GP-N and a multi-level controller such as 61F-G3N.

Basic Level Control

61F-GP-N

Choose this when you only need simple water level control, such as pump ON/OFF between two levels or a single high/low level alarm.

  • Suitable for simple tank level control
  • Good for 1 or 2 level points
  • Compact plug-in type controller
  • Common choice for basic pump start/stop applications
  • Cost-effective for simple control panels

Multi-Level Control + Alarm

61F-G3N

Choose this when you need pump control together with high and low water level alarm points. This is usually the better choice for fire water tanks, service tanks, and applications where multiple level signals are required.

  • Suitable for multiple level points
  • Can support pump control plus high/low level alarms
  • Cleaner setup than using multiple basic controllers
  • Recommended for 3-level fire water tank monitoring
  • Better for control panels with alarm outputs

61F-GP-N vs 61F-G3N: Which One Should You Use?

Selection Point61F-GP-N61F-G3N
Best forSimple level control Pump control with high / low alarm
Typical number of level points1 or 2 level points3 or more level functions depending on wiring and application
Typical applicationBasic tank full/empty control, pump start/stop, simple high or low alarmFire water tank, service water tank, refill tank, tank with high alarm and low alarm
When to chooseChoose when the customer only needs basic pump ON/OFF or one simple alarm outputChoose when the customer needs more complete monitoring, such as high level, refill control, and low level alarm
Panel designSmaller and simpler panel. Suitable for basic applicationsMore complete control panel. Suitable when alarm points must be clearly separated
Recommended for PS-5R?Yes, for simple applications using only some of the rodsYes, especially when using PS-5R for multi-level monitoring
Simple recommendationUse this for basic tank controlUse this for fire water tank / 3-level monitoring

Typical 3-Level Fire Water Tank Setup

For a fire water tank, a typical setup uses one common electrode and several level electrodes. The common electrode is normally the longest rod. The other rods are cut to the required alarm and control levels.

Electrode LevelFunctionTypical Action
High AlarmDetects overfill or high water conditionTrigger high level alarm, indicator lamp, BMS input, or alarm panel input
Stop RefillNormal full levelStop refill pump or close inlet valve
Start RefillNormal low operating levelStart refill pump or open inlet valve
Low AlarmLow water reserve warningTrigger low level alarm, fire alarm monitoring input, or BMS input
Common ElectrodeReference electrodeUsually the longest rod, extending below the lowest detection point

Practical recommendation: For a 3-level fire water tank application, use the PS-5R electrode holder together with a multi-level controller such as 61F-G3N. This gives a cleaner solution for refill control plus high and low level alarm.

How to Select the Correct 61F Controller

Step 1: Count the Required Levels

If you only need simple pump ON/OFF, 61F-GP-N is usually enough. If you need high alarm, normal control, and low alarm, use 61F-G3N.

Step 2: Check Cable Distance

If the tank is far from the control panel, a long-distance version may be required. This is important for rooftop tanks, remote tanks, and large facilities.

Step 3: Check Water Conductivity

Conductive level controllers require the liquid to conduct electricity. Normal tap water is usually suitable, but very clean or low-conductivity water may need a high-sensitivity model.

Other 61F Variants You May See

Besides the normal general-purpose models, 61F controllers may also come in special versions depending on site conditions.

Variant TypeMeaningUse When
General-purposeStandard model for normal conductive water level controlNormal tap water, tank control, refill pump control
Long-distance typeDesigned for longer wiring distance between tank electrodes and controllerTank is far away from the control panel
High-sensitivity typeMore sensitive detection for lower-conductivity liquidClean water, rainwater, purified water, or weakly conductive liquid
Low-sensitivity typeLess sensitive to leakage current, condensation, foam, or wet cable pathsNoisy environments or sites with false triggering problems
Two-wire typeSpecial wiring method for reducing electrode wiringUse only when matched with the correct two-wire electrode holder / application

Quick Recommendation

Choose 61F-GP-N if…

  • You need simple water level control.
  • You only need pump ON/OFF between two levels.
  • You only need one high or low level alarm.
  • You want a compact and cost-effective controller.

Choose 61F-G3N if…

  • You need 3-level water tank monitoring.
  • You need pump control plus high and low alarms.
  • You are monitoring a fire water tank or service water tank.
  • You want a cleaner solution than using multiple basic controllers.

Important note for fire water tanks: Fire water tank alarm and control requirements may be subject to project specifications, local authority requirements, fire code requirements, and licensed fire protection contractor approval. Always confirm the final control logic and alarm connection with the project consultant or qualified contractor.

Executive Protocol

Executive Protocol, also known as EXE, Exec or Protocol A, is one of the classic communication standards used between vending machines and payment systems. It is especially well known in Europe and is still commonly found in older vending machines, particularly in markets such as Italy, France and Spain.

What Is Executive Protocol?

Executive Protocol is a vending machine communication protocol used to connect the vending machine controller with payment devices such as coin mechanisms, change givers and payment controllers. It was originally developed as a proprietary protocol by Mars Electronics International, also known as MEI, and became widely adopted in the vending industry.

In many vending machine installations, Executive Protocol is used to manage payment credit, product pricing, vend authorisation and communication between the vending machine and the payment system.

Simple explanation: Executive Protocol is the communication language used by some vending machines and payment systems to decide when enough money has been inserted and whether the machine should allow a product to be dispensed.

Common Names for Executive Protocol

Depending on the machine manufacturer, payment system supplier or technical manual, Executive Protocol may be referred to using different names.

The full name commonly used in vending machine manuals and payment system documentation.

EXE / Exec

Short form used by many vending technicians and machine suppliers.

Protocol A

An alternative technical name often associated with MEI / Mars payment system documentation.

Why Executive Protocol Is Important

Executive Protocol remains important because many vending machines in Europe were designed around this payment interface. While newer machines often use MDB, there are still many machines in the field that continue to use Executive Protocol.

This is especially relevant when upgrading an older vending machine with modern payment systems such as cashless card readers, QR payment terminals, telemetry devices or remote monitoring systems.

  • It is widely used in older European vending machines.
  • It is commonly associated with Italian vending machines.
  • It is often found in machines using older coin mechanisms or payment controllers.
  • It may require an adapter when connecting to modern MDB-based cashless systems.
  • It is useful to understand when repairing, retrofitting or upgrading vending machines.

Executive Protocol in Europe and Italy

Executive Protocol is commonly found in European vending machines, especially in countries such as Italy, France and Spain. In the Italian vending industry, Executive Protocol has historically been very popular, and many technicians consider it one of the dominant protocols used in older Italian vending machines.

Industry observation: It is often said within the vending industry that a very high percentage of Italian vending machines use Executive Protocol, with some estimates claiming around 90%. The exact percentage can vary depending on machine age, manufacturer, location and whether the machine has been upgraded to MDB or cashless payment systems.

For this reason, anyone working with Italian vending machines, imported European machines or older coffee and snack vending machines may need to understand Executive Protocol.

Executive Protocol vs MDB

Executive Protocol and MDB are both vending machine payment communication protocols, but they are not the same. MDB is now more common in modern vending machines, while Executive Protocol is more commonly associated with older European vending systems.

FeatureExecutive ProtocolMDB Protocol
Common NameExecutive, EXE, Exec, Protocol AMDB, Multi-Drop Bus
Typical UsageOlder vending machines, especially in EuropeModern vending machines worldwide
Common RegionEurope, especially Italy, France and SpainGlobal vending market
Payment System RoleThe payment system has a strong role in controlling vend credit and permissionThe vending machine controller usually acts as the main controller and polls MDB devices
Cashless UpgradeMay require an Executive-to-MDB adapter or compatible cashless deviceUsually easier to connect to modern card readers, QR payment terminals and telemetry systems
Best ForMaintaining or upgrading older European vending machinesNew vending machine designs and modern cashless payment integration

Is Executive Protocol Open Source?

Executive Protocol was originally created as a proprietary vending machine protocol. Over time, as the protocol became widely used and many older machines remained in service, information about the protocol became more accessible to technicians, payment system suppliers and vending machine developers.

Today, Executive Protocol is often treated as an open or publicly documented legacy protocol in practical vending machine work. This makes it possible for repairers, retrofitters and equipment developers to support older machines that still rely on Executive communication.

Important note: “Open source” and “open protocol” are not always the same thing. Executive Protocol is better described as a widely documented legacy vending protocol rather than software source code. When developing commercial equipment, always check the actual protocol specification, electrical interface and any relevant compliance requirements.

MDB to Executive Protocol Converter

One common challenge is connecting modern MDB-based payment devices to older vending machines that use Executive Protocol. In this situation, an MDB to Executive Protocol converter can be used as an interface between the modern payment system and the older machine.

A converter board may translate communication between MDB and Executive Protocol, allowing the vending machine to work with newer cashless payment terminals, card readers, QR payment systems or telemetry devices.

  • Connects modern MDB payment devices to older Executive vending machines.
  • Translates payment credit and vend authorisation signals.
  • Helps extend the useful life of older European vending machines.
  • Allows upgrade paths for cashless payment and remote monitoring.
  • Can be useful for vending machine retrofit and repair projects.

When Do You Need Executive Protocol?

You may need Executive Protocol knowledge when working with vending machines that do not support MDB directly, or when the existing payment system is based on Executive communication.

Common situations include:

  • Replacing an old coin mechanism in a European vending machine.
  • Adding a cashless payment terminal to an older machine.
  • Repairing an Italian coffee, snack or drink vending machine.
  • Connecting a telemetry system to a vending machine using Executive Protocol.
  • Building an adapter between Executive Protocol and MDB.
  • Developing a custom payment controller for older vending machines.

Executive Protocol Adapter and Upgrade Considerations

Many modern cashless payment devices are designed around MDB because MDB is widely supported in newer vending machines. If the vending machine only supports Executive Protocol, an adapter may be required.

The adapter may perform one of the following functions:

  • Convert Executive Protocol to MDB.
  • Allow an MDB cashless reader to work with an Executive vending machine.
  • Translate payment credit and vend commands between the two systems.
  • Provide compatibility between old vending machines and modern payment terminals.

Practical recommendation: For a new vending machine project, MDB is usually the better starting point. For supporting older European vending machines, Executive Protocol support can be added as a compatibility feature or through a dedicated adapter.

Technical Points to Check

Before connecting to an Executive Protocol vending machine, it is important to check the machine manual and payment system documentation. Different machines and payment systems may have different wiring, connector pinouts and configuration options.

  • Connector type and pinout
  • Voltage level and power supply requirement
  • Executive / EXE mode setting in the vending machine
  • Payment system compatibility
  • Vend price configuration
  • Credit handling and vend authorisation behaviour
  • Whether the machine supports MDB, Executive, BDV or multiple protocols

Summary

Executive Protocol is an important legacy vending machine communication standard. It is especially relevant in Europe and is commonly associated with Italian vending machines. Although MDB is now more common in modern vending machine designs, Executive Protocol is still important for servicing, upgrading and integrating payment systems with older machines.

For businesses working with vending machine payment systems, understanding Executive Protocol can help when upgrading old machines, adding cashless payment, troubleshooting coin mechanisms or designing protocol adapters.

Pressure Switch

A pressure switch is a practical and reliable sensor used to monitor and maintain water pipe pressure in pumps, water systems, tanks, and piping installations. It helps detect pressure changes and automatically triggers connected equipment when the pressure reaches a preset pressure level.

We supply pressure switches suitable for industrial, commercial, and general water pressure control applications in Singapore.


What Is a Pressure Switch?

A pressure switch is a control device that responds to pressure in a pipe or system. When the water pressure rises or drops to a preset value, the pressure switch opens or closes an electrical contact.

This allows the switch to control pumps, alarms, indicators, or other equipment used to maintain safe and stable water pressure.

Common Applications

  • Water pump pressure control
  • Water pipe pressure monitoring
  • Booster pump systems
  • Water tank pressure systems
  • Industrial water piping
  • Building maintenance systems
  • Automatic pump start and stop control
  • Pressure safety monitoring

How It Helps Maintain Water Pipe Pressure

In a water pipe system, pressure may change due to pump operation, water usage, leakage, or system demand. A pressure switch helps monitor these changes and sends an electrical signal when the pressure reaches the preset value.

For example, when the pipe pressure drops below a certain level, the pressure switch can activate a pump. When the pressure reaches the desired level, the switch can stop the pump. This helps maintain consistent water pressure and protects the system from unnecessary pump operation.

Key Features

  • Reliable pressure sensing for water pipe systems
  • Suitable for pump control and pressure monitoring
  • Helps maintain stable water pressure
  • Can be used for automatic start and stop control
  • Compact and easy to install
  • Suitable for commercial and industrial applications
  • Available in different pressure ranges
  • Durable design for long-term operation

Why Use a Pressure Switch?

A pressure switch is useful when you need a simple and effective way to control equipment based on water pressure. It reduces the need for manual monitoring and helps protect pumps and pipe systems from pressure-related problems.

It is commonly used in water supply systems, pump rooms, industrial equipment, and building maintenance applications.

ICSP Circuit Design for Microchip microcontrollers

This page provides standard ICSP circuit design references for Microchip microcontrollers in SSOP-28, TSSOP-14/20, and SOT23-6 packages. These schematic blocks are intended for direct reuse in new designs, helping engineers implement a proven programming interface quickly and consistently.

Introduction

In-System Programming and Debugging (ICSP) is the standard method used to program many Microchip microcontrollers directly on the target board. Because the ICSP connection is widely used across products and projects, engineers often look for a proven reference circuit that can be copied into a new design with minimal modification.

This page provides standard ICSP circuit design references for common Microchip microcontroller package options. The goal is to give hardware designers a quick and reliable starting point for schematic capture and PCB design, while helping maintain programming compatibility, debugging access, and good signal integrity.

The reference circuits shown here cover three common package groups from Microchip microcontroller:

  • SSOP-28
  • TSSOP-20 / TSSOP-14
  • SOT23-6

These circuits are intended as standard implementation examples for typical engineering use. In most cases, they can be copied directly into a design and then adjusted only as needed for product-specific power, reset, connector, or layout requirements.

Standard ICSP Circuit Design Reference

This section collects standard ICSP schematic references for commonly used Microchip microcontroller packages. These designs are intended to support fast development and consistent implementation across projects.

Each reference circuit includes the essential connections required for device programming and, where applicable, debugging:

  • VPP / MCLR
  • VDD
  • VSS
  • PGD (Program Data)
  • PGC (Program Clock)

Depending on the device family, additional considerations such as pull-up resistors, decoupling capacitors, isolation resistors, or shared application pin usage may also apply.


Design Objective

The purpose of these reference circuits is to:

  • provide a known-good ICSP implementation
  • reduce schematic design time
  • improve consistency across hardware platforms
  • minimize programming and debugging issues during development and production
  • give engineers a circuit they can confidently reuse in new designs

These references are especially useful when the ICSP pins are multiplexed with application I/O and the designer needs a practical, standard connection approach.


General ICSP Design Guidelines

When using these reference circuits, the following practices are recommended:

1. Keep the ICSP interface accessible

Always provide a clear connection path to the programming tool through a dedicated header, test pads, pogo-pin interface, or production fixture.

2. Protect MCLR / VPP behavior

The MCLR/VPP line must support both normal device reset behavior and programming voltage entry requirements. Use the recommended pull-up network and avoid excessive loading on this pin.

3. Manage shared PGC and PGD signals

If PGC and PGD are also used by the application circuit, ensure connected circuitry does not interfere with programming or debugging. Isolation resistors may be used where needed.

4. Place decoupling capacitors close to the device

Power stability is important during programming and normal operation. Place bypass capacitors close to the microcontroller power pins.

5. Keep routing short and clean

Route ICSP signals with short, direct traces where possible. Avoid unnecessary stubs, heavy capacitive loading, or strong pull devices that can affect signal quality.

6. Verify connector orientation and pin definition

Use a consistent ICSP pinout and clearly mark the connector orientation in the schematic and PCB silkscreen to prevent programming errors.

How to Use These References

These ICSP reference circuits are intended to be copied directly into new designs as standard schematic building blocks. Before release, the designer should still confirm the following against the selected microcontroller datasheet:

  • programming pin assignment
  • MCLR/VPP requirements
  • supported debug interface behavior
  • supply voltage requirements during programming
  • any package-specific limitations
  • any family-specific recommendations from Microchip

Using a standard reference reduces risk, but final validation should always be completed for the exact device being used.

Automated Trellis Shade Control System

An Automated Trellis Shade Control System is becoming increasingly popular in Singapore due to the city’s hot climate, strong sunlight, and frequent sudden rain. These systems feature a smart roof structure—typically built with aluminium louvers or retractable fabric—that can open or close automatically depending on weather conditions.

Product Information

Product of Sunshade Trellis System Pte. Ltd. (Singapore)
Visit website: https://sunshadetrellis.wixsite.com/home

How the System Works

The trellis is powered by a motorised mechanism that allows the louvres or fabric panels to turn open for ventilation or sunlight and close completely for protection. When the system is in the sun shade position, it reduces heat gain on balconies, patios, and rooftop terraces.

Because the system is automated, it can operate on its own without user input. Sensors monitor environmental conditions, and the trellis will auto-close when rain is detected. This is especially useful in Singapore, where showers often come unexpectedly. At the same time, the roof can open automatically when conditions are safe, allowing airflow and natural daylight.

Trellis is an alternative to an awning for those who prefer a solid structure that can withstand wind and rain.

Key Features

  • Automated open/close control through remote, wall switch, or mobile app
  • Weather sensors that trigger auto-close when it rains
  • Adjustable louvre angles that let users turn open the roof partially or fully
  • Effective sun shade during peak afternoon heat
  • Strong, durable structure suitable for tropical climates

Why It’s Ideal for Singapore

Outdoor living spaces in Singapore—from HDB balconies to landed patios—benefit greatly from flexible weather control. An automated trellis enhances comfort by blocking heat, keeping areas dry, and providing a reliable shade solution that adapts instantly to changing skies.

Battery Replacement

The system uses SLA (Sealed Lead Acid) battery as a means to drive the DC geared motor. Typical installation uses 12V 7Ah SLA battery. You can also use a smaller SLA battery rated 12V 1.3Ah.

These batteries can usually last for years, but they do wear off over time.

A typical full charge voltage measurement is expected to be between 13V to 13.8V. This is a healthly voltage level. When the voltage of the battery is measured below 12V, it is likely that the battery is worn and requires replacement.

Please handle the battery with care. Connect the correct polarity to the battery terminal. Please handle with care, and do not to short the positive (+) and the negative (-) terminal of the SLA battery, as it can catch fire instantly.

Motor Replacement

The motor used for this Trellis is a 12V geared DC motor (7 gear teeth version) that is typically used for the vehicle winding windows. It is important to note that there is a Left and Right versions of the motor.

The tools required to remove the motor panel is mainly a 10mm spanner and an Allen key set. The motor panel has to be dismounted in order for the motor to be replaced.

Trellis panel install calibration

These Trellis controllers are designed for simple installation without using any limit switch to set the motor motion boundary.

The Trellis calibrated position has its panel opened to 90 90-degree angle. At this angle, the gear teeth should be hitting the boundary limit stud. At the calibrated position, tighten the two M6 hex screw to lock the lever in position.

The panel’s closed position will naturally set the limit boundary. The panel will be closed tightly, resulting in a current surge which becomes an indicator for the controller to stop the motor.

Structured Wiring

Home automation is getting more and more popular nowadays. Automation simplifies our daily task in our home, making our life easy.

Home automation may seems to be a science fiction or high tech stuffs that most people will not be able to afford. In actual fact, it has already penetrate into almost all our homes.

Nearly all household in Singapore has some form of home automation. Washing clothing used to be a chore in the past. The invention of a washing machine automate the washing chores. Rice cooker, microwave and vacuum cleaner appliances which has become a part of our daily life, shortening our time to do household chores. Women in the past stay at home to do house work, while the men work outside for an income. Automation has helped to transform the women in today’s society, allowing them to walk out of their house, joining the working force. The doubling of the work force has significant contribution to an economy. These invention that automate our home frees our time and change our society in many many ways.

Home automation has comes a long way and is still finding its way into our home. Our current era is very much involved with information technology. Most of the household have internet connectivity and it has becomes one of our latest household utility besides our electricity, water, and telephone bills.

The current home automation trend focus on information connectivity of the home. The industry believes that consumer wants a digital connection to control whatever a consumer have at home. Providing the consumer with the power of control. These comes in the form of remote lighting control, motorised curtain/blind control, air-con/fan control or automated opening of door.

Green environment and energy saving is another popular trend that pushed home/office automation. The industry comes up with product integrated with sensors that will automatic switches off lights when no one is around, or maintaining a constant lighting intensity throughout the day. Energy efficient automated solution is also a popular theme.

 

 

STARhome is a smart home program initiated by A-STAR. I used to work with STARhome, a smart home filled with many many latest technologies, many of which are not yet available in the market.

We had technologies like face and voice recognition which can authenticate its owner and automatically open the door for you. Automated news/sports video indexing, which segment out the clip that you are interested to watch. Voice/gesture command or mobile phone to control the lighting and appliances. Robot that listen to your command and serve you a cup of freshly brew coffee. Tracking your location in the home, streaming your favorite music where ever you go. Keeping track of your groceries inventory, so that you will never run out of your favorite food. A real time language translation device which helps translate any speech to Mandarin for my grandmother at home who is unable to understand an English speaking sales-person. A bed/chair/toilet bowl that keeps track of sleeping pattern and health condition. Video/Audio surveillance system which is able to detect elderly/children fall, or any other activities at home, notifying the home owner events that they are interested in. Self sustaining and maintainence aquarium (fish tank). A platform where smart devices communicate with one another within a home. There are many more smart little gadgets.

We have collected our experience working and living in a smart home and managed to build another one, STARhome@fusionopolis.

These technologies may seems science friction, but are already possible. They are however still not within the reached of common user like you and me. Having the opportunity to work in STARhome has provided me some insight to what a smart home means to me. A smart home that is affordable, simple and easy to use. Just like how a washing machine came into our home.


 

Most home automation that I have seen and worked with in the market are quite impressive and contains a lot of functions. However they do not meet the smart home definition that I have in mind. Affordable, simple and easy to use. Many smart devices that are available in the market are suppose to make our life easy, but very often, I find it is even more difficult to setup and use. Even a television set that has been evolving for decades, seems more and more complex to use. The number of buttons are growing on the remote control, the functions are getting difficult to set.

Compare to an old television, the television now has more functions, but requires more steps to get a simple task done. Very often, I will have to help my parent and elderly to setup or even use the new television. The elderly may have aged, but they can still manage simple old appliances which are easiler to use.

Innovation like a thermo flask has once overwhelm me. There is a time when I spent quite a long time trying to figure out how to get the hot water out of the flask for my cup of 3-in-1 coffee. There was so many buttons on the flask and they have really confused me, making me looking like an idot. Making an electronic engineer who is working with the latest technologies, looking like an idot. The old mechanical thermo flask has only two button at most. One big push button on the top of the flask to pump out the hot water, and another one to lock the pump (for safety in case children play with the flask and get themselves scalded).

Most of the high tech stuffs reallys piss me off, because they are not designed for wonderful user experience; it is design for the seek of looking high tech. The experience has rised my awareness for a better user experience.

I would like to delicate this page to talk about the stuffs that I would like see in a automated home. Pros and cons of the existing concept of smart home gadgets available on the market. Also important things to take note when building your dream home in Singapore. Many interior designers and contractors are still green in the area of home automation, so it is important to know what you want to look for in your home. It is you who are living in your home after all.

Structured Wiring

Smart home automation is becoming part of our home utilities, and it is important to design the infrastructure of your home to cater for the coming technologies trend. Provision wiring to meet future demands can save you cost.

The reason for provisioning the infrastructure is to avoid re-laying the cables. It is unlikely to have any further changes to the wiring, the access to the cable trunking should still be accessible. You can hide the cables but try not to seal it. Maintenance is necessary at times.

Structured wiring or cabling is a set of standard to lay the cable infrastructure, to ensure that interference is minimum. There are a few types of cable services that we can have in our home.

– AC Power 110-230Vac
– Digital data (Network, broadband)
– Analog signal (TV RF antenna, telephone line, Audio/Video)

The digital data and analog signal cable should be laid a distance of about 60mm away from the AC power line. This is to prevent noise from the AC power to be coupled over to the cables carrying digital and analog signal, especially when they run in parallel. It is also good to have the signal cables shielded to minimise the interference.

Sometimes when you switch on and off our electrical appliances or lights, you may notice that your television or radio can get disturb. For new television set, your may notice that the picture gets halt for a split seconds. The spark generated from the switch get coupled into the line. There will be no spark when the AC is at its zero crossing when it switched, but the probability is low being about to switch near the zero crossing period. A soft switch or electronic switch can minimised such spark, generating less noise.

When the AC power line and signal cables has to laid parallel to each other, it is good to keep them at least a distance of 60mm apart. Cables section that are not in parallel have less interference effect compare to those in parallel.

http://www.ehow.com/how_7934045_install-structural-wiring.html


Label of the cables is a good practice which minimise any inconvenient in future. Contractors do not bother to label the cables, because they are able to remember and managed them. As more and more cables are laid over the years, it can get more and more messy. Future contractor will have a hard time tracing the cables. It is always good to label the cables especially for structured wiring because there will be more variety of wiring which are more complex than before.

In Singapore, structured wiring can often be found in office and factory buildings, but is not adopted for home use. It is still a relatively new things for the home industry.

The typical wiring infrastructure that are adopted in our Singapore home are mainly:
– 230Vac cables (40-60A for HDB flats)
– TV RF/antenna cable
– Telephone cable

Fiber optic cable is available but not a popular choice. This is maybe due to the cost compare to other options.

In older homes, TV and telephone cable services are laid only to the living room;only the power cable is available at each room. Today with cheaper electronics products, consumers have the luxury to have more than one appliances in the same house. Each home is expected to have more than one telephone and television. It is now a common trend to see the TV and telephone cable laid to every room.

As technology evolve, the trend is starting to change. According to the statistic of Singapore 2012, there is a declining trend of household subscribing to the telephone line. This may be due to the popularity of personal mobile phone; at about 1.5 mobile phone per person. There are also new digital phone services which uses broadband to deliver voice call instead of analog phone line; the service is cheaper compare to the telephone line.

RJ11 (6pins) socket for telephone line (UK wall panel)

 


Recommended UK wall panel RJ45 (8pins) socket which is suitable for network (RJ45 jack) and telephone line (RJ11 jack) use, RJ45 jack

Telephone line is is declining. Every individual has at least a mobile phone. Telephone line (land line) that already installed are declining slowly. Most young family prefer not to install a new telephone line, as they are contactable through their mobile phone number.

Statistics on Telecom Services for 2012 (Jul – Dec)

See page ‘v’ of Report on the Household Expenditure Survey 2007/08

 

Telephone line may seem to be outdated, but I will still recommend the installation of infrastructure to support it. The recommendation is to install network cables instead of telephone cables. Network cable is able to host a number services like Ethernet, telephony, audio and video. This makes it a very flexible infrastructure to have.

Telephone lines do still have its unique advantages, compare to other new alternatives. Telephone line is linked directly from the phone exchange centre. The analog telephone do not requires additional power in order to work because the power comes from the telephone exchange centre. This means that in times of electricity failure, your analog phone will still works. Using a IP phones requires broadband internet and needs to be powered up from your wall power socket outlet. Using a mobile phone requires battery power. The number of mobile connection is also limited with a wireless cellular network. Power or internet connection failure will means that you will not be able to make call..

Not every household will want to install telephone line, but most will need network access in this information technology era. A recommended advise will be to laid network cables instead of the telephone lines. Network cables have 4 wire pairs which can be used for network as well as telephone purpose. Whether or not you will be using a telephone line, it is good to lay network line.

The network cables can support both the network and telephone services. RJ45 (8pins) socket is used for network cables, while RJ11 (6pins) socket is used for telephone lines. It is recommend to use a RJ45 socket, which RJ11 jack can also plug in.

The network cable has a number of grades indicating how the cable is shielded as follows,
CAT5 – no shielding
CAT5e – shielding over the cable (recommended)
CAT6 – shielding over each of the 4 twisted pair
CAT7 – shielding over the twisted pair as well the the cable

Technical information about the cable can be found here.

Laying CAT5e for the home will be more than good enough, for its performance and price. CAT7 will definately be too much. Installation using CAT6 or CAT7 cables can be quite difficult for a home, as the wire is usually thick which is difficult to install. CAT5 provide no shielding which performance can be degraded when it is laid near any noisy wires or devices.

The cables should be laid from each point to a central location where your network equipment (router) is likely to be placed. In a typical Singapore home, it will be either at the electrical box, or besides the TV console in the living room. It is recommended to lay 2 sets of cables for each location. The spare cables be use for telephone line or spare network lines, audio/video signal future use. You will never know when you will need it. It is better to provision extra cable which is cheap, compare to a wireless solution which is expensive and poor in quality.

 


DLINK DIR-655 WiFi router

A popular alternative to using network cables is wireless. Wireless network is convenient and easy to install, especially for existing home where it is difficult to lay new cables. Many consumers prefer to rely on wireless technology for their network services. Wireless tends to use more power and have limitation in the coverage they can support. The wireless signal can cover a distance of 30-50m under open space. The signal will find it hard to penetrate Singapore HDB flat, reducing the distance to about 10-15m. Many of my neighbors are also using WiFi in their home. At the time I am writing now, my WiFi dongle is able to detect 36 WiFi station. WiFi has a limited bandwidth over the air medium. With this limited channels across the air sharing with sharing with the desktop and laptop, the communication can be slow and drop connection can often occurred. There is also a higher possibility of being hack, compared to wired network. As far as possible, physical cable is still my preferred choice.

There are reports which indicate that wireless can cause health hazard. For consumers who are sensitive to radio frequency exposures, they may find it more comfortable with wired network. The same theory applies to the cellular phones. Many research have been produced with respect to these danger.

For me, I do still use it, but will try as much as possible to avoid it.

 


Aztech power line communication modem


TP-LINK PLC modem

Power line communication is also a popular choice. The network communication is done with the house existing power line. The communication is done within the home power line. Similar to WiFi, it is useful if it is troublesome to lay new wiring.

Wired ethernet network is still the best.
