Water 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 MΩ. 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

Sensor maintenance
The sensor has an analog output that should be connected to the pin of the A/D converter (analog input in Arduino). This will allow you to measure the proportional voltage signal to determine the fluid level.
| PIN | DESCRIPTION |
|---|---|
| VCC | The supply voltage of 5 V. |
| GND | The ground of the system. |
| AOUT | Analog output with the voltage proportional to the liquid level. |
