How the Rain Drop Sensor Works

The module consists of a rain detection board with conductive traces and a control module:

• When rain drops fall on the sensor plate, water bridges the conductive tracks.

• This reduces resistance and changes the output voltage.

• The control module processes the signal and provides digital and analog outputs.
