Water Leak Detector

Tax included

The water leak detector is designed to detect an emergency water leak situation. When the water immersion level touches the sensor probe,  the  built  in  relay  will  switch  on  and  shut  down  equipment  in  the  house  or  turn  on  the  alarm  system.This  control  circuit  has  an  very  low  potential  energy,  so  it  won't  cause  any  ignition  of  flammable or combustible materials

Wiring Diagram

Please refer to the pin information below:

  • Red wire and brown wire ---- VCC+ and VCC-
  • Yellow wire ---- Relay common pin
  • Blue wire ---- Relay normal closed pin
  • White wire ---- Relay normal open pin



•  The probe pole of the sensor is placed facing down to the ground vertically. The sensor should be placed in the lower spot in the flat area.

•  If you need to detect a small amount of water (not to a certain depth), it's a good practice to place a sponge tray under the probe.
