Thingsee LEAKAGE RUGGED installation instructions


Thingsee LEAKAGE RUGGED detects liquid underneath the device. The sensor detects a solid water layer between the two detection pins at the bottom of the device. The product is placed on the floor or place of potential leakage risk pins down.

The sensor can be used for leakage detection on floors, flat surfaces and pipes where flooding, leakage or even condensed water may take place.

Thingsee LEAKAGE RUGGED uses event based messaging where measurement is done every 30 seconds. In case there is a change to the previous measurement, the measured value will be reported immediately. In case the measurement value remains the same, it’s reported once in every 1 hour.

Please note that the measurement values highly depend on the liquid in question: for example, clean tab water and salty sea water give different values. We recommend the location to be checked for leakages every time a high decrease of the measurements value is observed.

General installation instructions

Install the sensor on the floor or surface where leakages, moisture or flooding is a concern.

Pipe leak detection

Install on a pipe with sponge/foam in between the pipe and the device. Attach with a cable tie.

Things to avoid in installation

Avoid installing Thingsee products near the following

  • Thick concrete structures or thick fire doors
  • Electrical transformers or thick electrical wires
  • Escalators
  • Nearby heating or cooling devices and/or vents
  • Direct sun light
  • Nearby halogen lamps, fluorescent lamps or similar lamps with hot surface
  • Nearby radio equipment like WiFi routers or any other similar high power RF transmitters.
  • Inside or underneath a metal cabinet or box
  • Near elevator motors or similar targets causing a strong magnetic field


Please make sure the Thingsee gateway device is installed before you install the sensors.

To identify the sensor, read the QR code on the front of the device with a QR code reader or Thingsee installation application on your mobile device.

Identifying the device is not necessary, but it will help you keep track of your IoT installation and help Haltian support to solve possible issues.

Before installation, the sensor is in low power mode and the LED indicator on the sensor blinks dimly every second. Note that with white device casing, the LED blinking is difficult to see. The sensor is switched on with the magnet switch tool by holding it against the sensor’s magnetic switch.

Hold the magnet switch tool against the sensor until the LED indicator starts to blink brightly for one minute. When the LED goes off, the sensor is switched on.



Use the Pontoon accessory to float the device in the case of a flood. This will also support the device to sit firmly on the floor and not to turn over accidentally.

Now you are ready to place the sensor where needed.
