Simulation of Arduino Based Rain Detector in Proteus

A rain detector based on Arduino is a simple electronic device designed to detect the presence of rain or moisture in the environment. It typically consists of a series of sensors, usually in the form of conductive plates or wires, connected to an Arduino microcontroller board. When raindrops or moisture make contact with these sensors, they create a conductive path, allowing the Arduino to detect the change in resistance and infer the presence of rain.
