Rain Drop Sensor Module
Description:
Rain Drop Sensor Module is a weather-sensing device designed to detect water droplets, making it ideal for projects that require real-time monitoring of rainfall or surface moisture. It consists of a rain detection board (sensor plate) and a control module with signal processing circuitry that outputs both analog and digital signals, allowing for versatile use with a wide range of microcontrollers including Arduino, ESP32, Raspberry Pi, and others.
Features:
1. Detects rain or surface moisture
2. Dual output: analog and digital
3. Adjustable sensitivity via onboard potentiometer
4. Works with most microcontrollers
5. Low power consumption
6. Ideal for weather monitoring and automation systems
7. Simple plug-and-play design
