Description
The Rain Detection Sensor Module (Black) is a simple and effective sensor designed to detect rain, water droplets, or surface moisture. It works by measuring conductivity changes on the sensor plate when water comes into contact with it.
This module is widely used in Arduino and IoT-based projects such as rain monitoring systems, automatic wiper control, smart irrigation, and weather stations. It includes both a sensing plate and a control module with adjustable sensitivity.
The onboard comparator (commonly LM393) allows users to set a threshold for digital output, while the analog output provides real-time moisture level data. The module is easy to use and suitable for beginners as well as professionals.
