Water Level / Rain Sensor; It can measure water level up to 40mm and can be used as a rain sensor. When water comes into contact with the conductive lines on the sensor, it gives analog output. It is easy to use. You can use it with Arduino and many microcontrollers.

Look for the model that has a larger detection surface area and can also provide digital output. here.

Features:

•Operating Voltage: 5V

•Operating Current: <20mA

•Product Dimensions: 65x20x8mm

•Sensor Reading Area: 40x16mm
