Product Overview
The Rain Drops Detection Sensor Module is a reliable rain detection solution that senses both the presence and intensity of rainfall. Using a conductive sensing board, the module converts moisture contact into measurable signals suitable for a wide range of DIY and professional projects.
Why this rain drop sensor module?
- Detects light to heavy rain with consistent response.
- Offers both digital and analog outputs for flexible integration.
- Adjustable sensitivity to suit local conditions and thresholds.
Key Features
- High Sensitivity: Conductive traces on the sensing board change resistance when wet, enabling detection of small raindrops.
- Digital Output (DO): Provides a clean on/off signal for microcontrollers like Arduino and Raspberry Pi to detect rain presence.
- Analog Output (AO): Outputs a proportional voltage to measure rain intensity for logging and analysis.
- Adjustable Sensitivity: Built-in potentiometer lets you fine-tune the detection threshold for false-positive reduction.
- Power Efficient: Operates from a standard 5V DC supply for easy compatibility.
- Wide Operating Range: Functional from -20°C to 70°C for outdoor or sheltered environments.
- Compact Design: Small footprint for mounting on weather stations, rooftops, or mobile platforms.

Applications
- Weather stations and environmental monitoring
- Automated irrigation systems and smart gardening
- Outdoor equipment protection and cover automation
- Research projects and educational electronics kits
Integration and Wiring
Connecting the rain drop sensor module is straightforward. Typical wiring to a microcontroller:
- VCC -> 5V
- GND -> Ground
- DO -> Digital input pin (for rain/no-rain detection)
- AO -> Analog input pin (for measuring rain intensity)
When using with Arduino, read DO as a digitalRead for threshold events and read AO with analogRead to obtain a value proportional to moisture level.
Installation and Sensitivity Adjustment
- Mount the sensor in a location exposed to rain but sheltered from direct debris and splashing if possible.
- Power the module with 5V and monitor the DO and AO signals in your controller serial monitor.
- Turn the onboard potentiometer slowly until the DO output toggles at your desired rain threshold. Use AO readings to refine detection of light, moderate, or heavy rain.
Compatibility and Tips
- Designed for easy integration with Arduino, Raspberry Pi (with ADC), ESP8266, ESP32, and other microcontroller platforms.
- For long-term outdoor use, consider a protective, water-permeable coating or a small shelter that allows drops but reduces debris buildup.
- Calibrate sensitivity after installation to account for wind, splash, or environmental contaminants.
