Rain Drop Sensor Module Arduino UNO 5V~12V TTL control signal forRain Drop Sensor Module The rain sensor module is designed for accurate rain detection and environmental monitoring. This rain drop sensor is widely used to measure rainfall intensity and detect the presence of water droplets in real time. The rain sensor can be integrated into various weather monitoring systems and converts rainfall data into both analog (AO) and digital output signals, making it suitable for platforms like Arduino and other
