The Rain Drop Sensor Module is a high-sensitivity rain detection device designed for weather monitoring, smart irrigation, and automated outdoor systems. It consists of a rain detection board and a control module, which work together to detect water droplets or moisture levels on the surface. The sensor provides both digital and analog outputs, making it easy to interface with Arduino, Raspberry Pi, ESP8266, and other microcontrollers. When raindrops fall on the sensor, it changes resistance and sends a signal, which can be used to trigger alerts, control roof mechanisms, or activate irrigation systems. Made from corrosion-resistant materials, this sensor ensures long-lasting durability even in outdoor environments. Ideal for home automation, IoT weather stations, and agricultural applications, the Rain Drop Sensor Module is an essential component for smart weather-based automation projects.
