Rain Drop Sensor Module

The Rain Drop Sensor Module is a reliable water and rain detection sensor designed for weather monitoring, smart irrigation, automation systems, and DIY electronics projects. It can detect rain, water droplets, moisture, and liquid presence on the sensor plate, making it ideal for rain alarms, automatic wiper systems, smart farming, and environmental monitoring applications.

This module includes a high-sensitivity rain detection plate and an LM393 comparator control board with both analog and digital outputs. The onboard potentiometer allows adjustable sensitivity for accurate rain and water detection. It is fully compatible with Arduino UNO, ESP32, NodeMCU, Raspberry Pi, STM32, and other microcontroller development boards.

The Rain Sensor Module is widely used in IoT projects, weather stations, home automation systems, agricultural monitoring, and robotics applications. Its compact size, low power consumption, and easy interfacing make it suitable for students, hobbyists, makers, and embedded system developers.
