The Rain Sensor Module is a simple yet effective sensor designed to detect rainfall or water presence on its surface. It uses a PCB-based sensing plate where water droplets change resistance, which the onboard comparator translates into an analog or digital signal. This makes it suitable for academic research, IoT-based weather stations, smart irrigation systems, and environmental monitoring projects.
This sensor is widely used in IoT-enabled weather stations, smart irrigation control, agricultural research, and environmental monitoring systems. Researchers often integrate it with DHT22 (temperature/humidity) and BMP280 (pressure/altitude) to build complete weather research platforms. |
