Rain Sensor

A rain sensor is an electronic device used to detect rain or the presence of water. It consists of a sensing plate and a control module that detects changes in electrical conductivity when water or raindrops fall on the plate. The sensor can provide an output signal to a microcontroller such as Arduino, which can then perform different actions automatically. Rain sensors are commonly used in automatic clothes-drying systems, rain alarms, smart irrigation systems, automatic windows, and weather monitoring projects.
