Water Detection Sensor Module electret mic Github STM32H750 Development Board documentationWater detection sensor is used to detect water leak, water level or rains. This is obtained by having a series of parallel wires exposed traces. The sensor traces have a weak pull up resistor of 1 M. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace. The analog signal output can be read directly to arduino Specifications Operating voltage: 5V Operating current: less than 20mA Sensor
