Automated Awning Shade Wiring for Rain Sensor

Automated Awning Shade using a Rain Sensor

Automated awning will open its shade when the weather is raining, and retract the shade when the sky turns fine. A rain sensor is used to detect the rain. A switch can be wired for manual or automatic control of the motorised awning shade.

Automated Rain Sensor Awning Shelter.

Automated Awning Shade, Rain Sensor Wiring

An example of the automated awning rain sensor wiring for the automatic and manual control of the shade.

The cable to the outdoor rain sensor needs a minimum of 3 wires to work. A jumper wire can be wired inside the rain sensor to supply the 12V supply to the internal relay. This will enable the output (NO, normally open) to be energised when the rain sensor is activated. Hence a minimum of 3 wires is enough for the rain sensor. For a more flexible implementation, we will recommend 4-5 wires connection.

Check out the step by step rain sensor installation guide, for more details.

Rain Sensor Automated System Integration

Automatic rain sensing awning passenger waiting for a taxi


The automatic awning will be opened up when the rain sensor detects raining activity. The sensitivity of the rain detection can be adjusted.

If the rain activity has stopped, the awning will remain opened for about 2-3 minutes before it starts to retract the awning up. If a longer time period is needed, you can set the DIP switch no. 4 on the sensor to extend the resting time to 15 minutes.


Auto rain sensing or manual awning control switch


An operator can select “Auto” mode on the switch, which allows the rain sensor to open the awning automatically when it rains. The “Manual” mode allows the operator to manually open or retract the awning with the Up/Down switch on the righthand side.

You can refer to the wiring diagram as featured in the previous section above.

  • Wheatstone Bridge

Data Log Interface

There are a number of data interfaces to choose from. It depends on your application.

Data collecting using a memory card is suitable for a standalone application where you want to leave the system to do the measurement or monitoring. You can collect the data at a later time, and open the file with your Microsoft Excel or OpenOffice Calc software for manual data analysis. The logged data can be presented with a timestamp for your archive. The amount of data collected will depend on the data being logged, the memory size of the storage and the time frequency of each data sample.

For an application that requires real-time data collection or real-time data analytic, you should consider using Ethernet communication line. Ethernet communication system is also more efficient when you are collecting from a number of sensors deployed to various different location.

Timestamp of Data Logged

Date and time logging is typically necessary for analytic. This is also known as the data timestamp. This is especially useful for fast changing sensor data. Data logged can be archived for future reference.

Power Supply

The recommended method of powering up the data logging system is to use the wall mains 230Vac power supply.

For outdoor data collection, you may like to have your data logging system plugged to your vehicle for power or have it powered up from a battery.

A logger system can have the battery built in. There is a limit to how much power a battery can supply. For longer data collection usage, a large size battery will be needed. It usually means more bulky and heavy. There will be a charging function to charge up the built-in rechargeable battery.

PCB Board Fabrication

Introduction to PCB Board Fabrication

When submitting your design to a PCB fabrication factory, it is easier to submit the universal Gerber file format. Some factories do accept specific format from a particular software. You can easily generate the Gerber format of your PCB layout design through any PCB design software. Please indicate the following when submitting your PCB Gerber files to your PCB fabrication factory,

  • PCB Fabrication Specification
  • Quantity Required
  • PCB board size (if Gerber files is not available yet)

The information will help the fabrication house to reply you with a quotation promptly. The next few section provide the details that you need to know before approaching the PCB fabrication factory.

PCB Specification Specification

The PCB fabrication specification tells us how you would like your PCB board to be produced. For simple electronic circuit (2 layer board), we will usually recommend the following commonly used industrial grade PCB specification,

PCB specification:
FR-4, 1.6mm, 2L, 1 oz copper, Green Mask, White Silkscreen, HASL

If you would like to find out more details about the PCB specification above, check out this PCB fabrication specification page.

Quantity Required

PCB fabrication production quantity can be as low as 1 piece. As a general guide, the cost of each PCB board reduces as the quantity increase. There are works involve in setting up the machinery and process for the board production of a PCB design. You can specify the exact quantity that you need for your PCB board.

For the purpose of circuit prototyping, you may only need 1 or 2 pieces for testing. Our recommendation is to fabricate 5 pieces to cater for unforeseen rework or modification. The total cost of the fabrication job between 1-5pcs is not very significant.

A typical recommended quantity for PCB production, assembly work would be 5pcs, 10pcs, 25pcs, 50pcs, 100pcs, etc… These quantities tend to be more cost effective, in the various stage of the production process.

PCB Board Size

PCB board size is directly related to the material used. The cost for each PCB board is directly related to the cost. A bigger board will cost more than a smaller board.

Keeping the board small can help to reduce production cost and future cost (like product shipping, storage, etc…). For mass quantity production, it will make economical sense to design the board smaller.

Designing smaller PCB board can also mean a higher cost in PCB design. More thoughts and time will be needed to layout the components and traces onto a smaller board space. This higher cost in designing the PCB is usually negligible for high volume production.

Single Payment Terminal for Multiple User Station

For an application that has multiple machines serving the customers, it will be cost effective to consolidate the payment to a single payment terminal. A payment terminal (for example an Ezlink card payment) is typically an asset of the payment service provider. Each terminal can incur monthly rental and data connection charges. This charges can be significant over a period of time and will not be cost effective if the machine turn-over is low.

For user stations application where the payment terminal is not be used intensively, we can design a system to consolidate the payment for all your machines. This is like a retail store where the customers are served individually, and there is only 1 cashier counter opened to collect the payment from your customers. The monthly charges of the payment terminal can then be reduced, maximising your returns.
