RAIN SENSOR

A rain sensor detects water droplets and helps determine whether it is raining. It is commonly used in weather monitoring systems, smart irrigation, and automotive applications. The sensor consists of a conductive rain-sensing plate that detects water through changes in resistance. The module generates digital and analog outputs, making it compatible with various electronic circuits. It helps automate windshield wipers, greenhouse irrigation, and home automation systems. The sensitivity can be adjusted using an onboard potentiometer. The sensor responds quickly to rain and provides real-time data for accurate decision-making. It is widely used in automated outdoor systems to prevent water damage or optimize resource usage. Its compact design makes it suitable for embedded applications. It enhances smart weather-based automation and security solutions.
