Rain Sensor Module MH-RD with Control Board & Jumper Wires | Rain Drop Detection Sensor for Arduino & DIY Projects

The MH-RD Rain Sensor Module is a compact and easy-to-use rain and water detection sensor designed for Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontroller-based projects. It consists of a rain sensing plate and an LM393-based control board that detects water droplets and provides analog and digital output signals.

The sensor works by detecting changes in conductivity when water or raindrops come into contact with the sensing plate. The onboard sensitivity adjustment potentiometer allows you to set the desired detection threshold. The module can be used for rain detection, weather monitoring, automatic window systems, smart irrigation, water detection, robotics, and educational electronics projects.
