Water Leakage Sensor | Detection & Monitoring

This page explores the various type of water sensor for the detecting of water leakage. These sensors are commonly used to detect water leakage from aircon condensation.

Aircon condensation water leakage is a very common sight in the industry. This problem is normally due to improper design and installation of the water drainage pipes. Water drainage pipes installed were too small resulting in water clogged by dust or mould when used over time. Some water drainage pipe was seen to be installed in a anti-gravity manner, which makes it impossible for any water to drain out.

Custom Cable Tester

Cable tester, custom design for cable harness assembly production.

Custom cable tester electronic kit

An operator can just simply plug in the cable connector to the tester to check for the cable harness assembly automatically.

An audible beep will be sound immediately after the operator plug-in the connector. This indicates that the cable’s wiring is correct. The operator can simply focus their vision on the manual connection work.

If there is no sound heard after plugging in, the cable’s wiring is probably incorrect or faulty. There will be LED indicator (orange colour) for each of the respective wiring. If any LED remains lighted up after plugging in the connector, they indicate a wiring fault. The fault due to the following,

  • incorrect pin connection.
  • the wire break resulting in a broken electrical connection.
  • the connector is not properly crimped or soldered.

Wire harness connection tester device

This custom tester has a monitoring mode which is designed to catch intermediate break wire connection that may be potentially existing in your the cable assembly. Intermediate wire connection fault can be due to a broken wire or cable that is not properly assembled. The fault may occur when the cable is touched or bend too much.

When all the connectors are connected to the cable tester, the tester will automatically enter into a monitoring mode. You should be able to hear 2 special beep sound which indicates that the tester is now in the monitoring mode. In this mode, all connectors are connected to the tester. Any connection break in the process of monitoring will trigger an error from the cable tester device.

To test your cable assembly in this mode, you can simply shake up the whole cable. The shaking can help to bring out any intermediate connection problem if there is any. You should see an error LED indicator (Red) lights up together with a long Error tone if an intermediate connection break is detected. The respective wire connection indicator (Orange LED) will also be displayed to indicate the exact wire that is having the intermediate connection problem.

Features of the Cable Tester [PIC-023]

Wire connectivity indicator lights up for faulty wires

  • Simple to use.
  • Instant audio beep and flashing LED light (Green) when the cable is plugged in, to indicate that the cable has passed the checking.
  • LED indicator (Orange) will remain lighted to pinpoint faulty wires
  • Able to catch potential intermediate connection fault in the cable.
  • LED (Red) and long buzzer tone to indicate detected cable problem.
  • Portable and can be designed to power up from USB power supply or from the battery.

Operating Procedure

Test for intermediate cable connection fault

  1. Plug in USB power cable, or insert batteries.
  2. Switch on the cable tester to power up. A test sequence will run to show that the buzzer and all the LED are working.
  3. Plug in one side of the cable onto the tester.
  4. Plug in the other side of the cable. The cable tester will detect the connection and begin testing the cable.
  5. A double beep sound and flashing Green LED indicates that the cable is tested ok.
  6. The respective LED indicator (Orange) for each of the wiring will diminish if the connection is mated correctly.
  7. If there is no sound heard after plugging in the cable, the cable is probably faulty. Check on the respective wire indicator (Orange LED) to determine the exact wire that is faulty. 1 or more LED should be lighted up which indicates incorrect or no connection.
  8. After the cable is all connected to the cable tester and has passed the wire connection test, the tester will enter into a monitoring mode. You should hear 2 special beep, followed by a blinking light from the green indicator, which tells you that the tester is now in the cable monitoring mode.
  9. In this cable monitor mode, you can continue to test the wired connection of your assembled cable harness. Shake your cable to see if there is any intermediate connection fault can be caught. If a glitch is detected due to the intermediate connection break, the cable tester device will be able to catch it. A long beep and error indicator (Red LED) will be lighted up. The respective wire indicator (Orange) will also be lighted up to pinpoint the exact wire that is causing this intermediate connection problem.
  10. The caught wire glitch fault will remain until all the wires are disconnected. The cable tester will then reset the test procedure.
  11. The operator can proceed to test the next cable harness set.

Other Optional Specialised Test Features

For dedicated wiring for precision/importance use, there are optional test that we can design to help you detect potential faults in your cable harness wiring.

The following are some of the specialised test that you may need to test on your assembled cable beside the basic connectivity check.

  • Ohm test or resistivity test for your wires and connectors, to check if the wires are crimped or fasten properly.
  • High voltage test, to ensure the wires are properly insulated.
  • High-speed data or RF test to ensure signal integrity quality of your assembled cable.

CO2 Carbon Dioxide Sensor

A carbon dioxide sensor, also known as a CO2 sensor is a sensor for the measurement of carbon dioxide gas level. The most common technologies used for CO2 sensors are infrared gas sensors (NDIR) and chemical gas sensors.

Many application measures indoor air quality using a CO2 sensor. Carbon dioxide does not have smell or colour. For factory production that releases by-product gas like the carbon dioxide gas, CO2 sensors act as a safety sensor to prevent production workers from health hazards due to lack of oxygen. There are more industrial applications.

Electrode Water Level Sensor

Electrode water level sensor is also known as a “Conductivity Level Sensors”.

Electrode sensor basically requires a physical contact with the water to detect the water level. The water act as a resistance. Small electronic current will be passing through the water which helps the sensor to sense the water level. For this reason, not all liquid can use this sensor for detection. One example is the oil, which has an insulating property in nature. If you need to measure the level of a non-conducting liquid, consider using an ultrasonic water level sensor.

For a typical water tank or rain water level detection, the electrode sensor is an affordable and a commonly used method to detect the amount of water in a tank compared to other water level sensing method.

Electrode Sensor for Water Level Detection

An electrode sensing needs at least two contact point to function. For electrode with only a single probe, the other end of the sensor wire will be connected to a metallic tank (usually of stainless steel material). The metallic tank will act as the second probe. If the tank is not metal, or you do not want to connect the sensor wire to your tank, you can use a two probe electrode.

For multiple water level detection, you will need more probes. You can place up to a maximum of 5x probe for 3-4 water level detection. If you need to differential more water levels, you may like to consider using an ultrasonic water level sensor which can provide a higher resolution of detecting the water level.
