Product Description

The Raindrop Sensor / Water Drop Sensor Module is a simple and effective solution for detecting rain or water droplets. It works by sensing changes in electrical resistance when water falls on the sensor plate, making it ideal for rain detection and water leakage monitoring.

Operating on 3.3V to 5V DC, this module is fully compatible with Arduino, Raspberry Pi, ESP8266, ESP32, and other IoT platforms. It provides both analog and digital outputs, allowing users to measure rain intensity or trigger alarms and automation systems. The onboard LM393 comparator and adjustable sensitivity potentiometer enable precise control over detection levels.

Perfect for automatic rain sensing systems, weather monitoring projects, smart irrigation, water leakage alarms, and educational electronics experiments, this raindrop sensor module is widely used by students, hobbyists, and developers.
