This sensor can be used both as a water level (up to 40mm) measurement sensor for shallow waters and as a rain sensor.
An analog value can be read on the sensor output pin as a result of the contact of the conductor lines drawn parallel to each other with water. It can be used with many microcontroller platforms, especially Arduino. Using the sensor is very simple. By making the supply voltage and ground connection, reading can be made from the sensor output leg. If you are looking for a rain sensor with a larger detection surface area, click here.
