Raindrop Detection Sensor Module

The Raindrop Detection Sensor Module helps you sense rainfall or water splashes by using a conductive PCB plate. When water drops fall on the sensing area, it triggers a digital signal, allowing you to automate actions like closing windows, sounding alarms, or starting a water pump.

Perfect for smart home setups, weather stations, or greenhouse automation, this sensor is fully compatible with Arduino, Raspberry Pi, ESP32, and other microcontroller boards.

✅ Key Features:

🌦️ Detects raindrops, water presence, or surface wetness

🎚️ Adjustable sensitivity via onboard potentiometer

🔌 Outputs digital signal for easy microcontroller interfacing

🔋 Low power consumption

💡 LED indicators for Power and Output
