Grove - Water Sensor

Sale price$9.95


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

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.
