Description
- The Raindrop Sensor detects rainwater using changes in resistance or conductivity when water droplets form conductive paths on the sensor plate.
- The system consists of:
- Collector Plate: Detects raindrops and outputs variable resistance
- Control Module: Uses an LM393 voltage comparator to convert readings to analog or digital signals
- The sensor outputs:
-
- Analog signal proportional to rainfall intensity
- Digital signal (0/1) for rain/no-rain detection
- Commonly used in weather stations, smart irrigation, automatic window control, and safety automation systems.
- Enables smart automation such as:
- Closing windows or shades during rain
- Activating wipers in automotive systems
- Controlling irrigation based on real-time precipitation
- Provides real-time rain data for environmental monitoring and research.
- Designed to be durable, cost-effective, and easy to integrate with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontrollers.
