Rain Drops Detection Sensor Module

The Rain Drops Detection Sensor Module is a highly sensitive weather detection sensor designed to identify rainfall and water droplets. It works by measuring changes in resistance across a conductive sensing plate when water is present. This module is widely used in smart irrigation systems, weather monitoring stations, automatic windshield systems, and IoT-based environmental projects.

Features

• Detects rain, water droplets, and moisture presence
