The water Sensor detects the presence of water using exposed PCB traces. The sensor is made up of interlaced traces of Ground and Sensor signals. The sensor traces are weakly pulled up using 1 MΩ resistor. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the ground trace.

This circuit will work with digital I/O pins of Arduino or your preferred microcontroller. You cam also use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.


  • Rainfall detecting
  • Liquid leakage
  • Water level or overflow detector

Connect the module to your Arduino board or microcontroller using any of the digital pin. You can gain the value of the signal pin. When there is water on the bare conducting wires, the value is LOW. Otherwise, it will be HIGH.
