The Water Sensor module indicates whether the sensor is dry, damp or completely immersed in water by measuring conductivity

Overview

The sensor traces have a weak pull-up resistor of 1 MΩ.
The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace.
Believe it or not this circuit will work with the digital I/O pins of your Arduino or you can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.

Features:

  • Grove compatible interface
  • Low power consumption
  • 2.0cm x 2.0cm Grove module
  • High sensitivity

Application Ideas:

  • Rainfall detecting
  • Liquid leakage
  • Tank overflow detector
