Description
The Raindrop Sensor Module is designed to detect rainfall, water droplets, and surface moisture using a conductive sensing plate. When water contacts the sensor plate, conductivity changes are measured and converted into analog and digital outputs.
This module is easy to interface with Arduino, ESP8266, ESP32, and Raspberry Pi, and is commonly used in weather stations, rain alert systems, automatic wipers, and smart irrigation projects. Sensitivity can be adjusted using the onboard potentiometer.
