Description
The Water Sensor Module is part of the Grove system. It 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. You can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.
