Raindrop Rain Detection Sensor Module

The Raindrop Rain Detection Sensor Module is designed to detect the presence of rain or water droplets. The module consists of a rain-sensitive plate and a control board with an LM393 comparator.

When raindrops fall on the sensor plate, the resistance of the board changes. The control module detects this change and sends a signal to the microcontroller. The module provides both analog and digital outputs, allowing users to detect rain intensity or simply check whether rain is present.

This sensor is widely used in automatic rain detection systems, weather monitoring stations, smart irrigation systems, and home automation projects.
