The Water Sensor water level sensor is an easy-to-use, cost-effective water level/water drop identification sensor that determines the water level by measuring the water droplets/water volume with a series of exposed parallel wire traces. It is easy to complete the conversion of water quantity to analog signal, and the output analog value can be directly read by the Arduino development board to achieve the effect of water level alarm.
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 (S) | Analog output with the voltage proportional to the liquid level. |
