The Rain Sensor Module is a highly reliable and easy-to-use sensor designed for detecting rain or water. It consists of a rain detection board and a control board, making it ideal for various applications such as weather monitoring, automatic irrigation systems, and other rain-related automation projects.

Key Features:

  1. Rain Detection: Accurately detects the presence of rain or water on its surface.
  2. Dual Outputs: Provides both digital and analog outputs for flexible interfacing with different types of microcontrollers and systems.
  3. Adjustable Sensitivity: Features a potentiometer for fine-tuning the sensitivity of rain detection, allowing customization for different environmental conditions.
  4. Corrosion-Resistant Design: The sensing plate is designed to resist corrosion, ensuring long-term reliability and performance.
  5. Wide Operating Voltage: Compatible with both 3.3V and 5V power supplies, making it suitable for a wide range of microcontroller platforms, including Arduino, Raspberry Pi, and more.

Technical Specifications:

  • Operating Voltage: 3.3V – 5V
  • Output Type: Digital and Analog
  • Digital Output: High/Low (1/0)
  • Analog Output: 0V to VCC (depending on the amount of water detected)
  • Sensitivity Adjustment: Potentiometer on the control board
  • Dimensions:
    • Sensing Plate: Typically 5cm x 4cm
    • Control Board: Typically 3.2cm x 1.4cm
  • Connection Pins:
    • VCC: Power supply (3.3V to 5V)
    • GND: Ground
    • D0: Digital output
    • A0: Analog output


  • Weather Monitoring Systems: Integrate into weather stations to provide real-time rain detection and data logging.
  • Automatic Irrigation Systems: Prevents unnecessary watering by detecting rain, thereby conserving water and preventing over-irrigation.
  • Smart Home Automation: Automates actions such as closing windows, retracting awnings, or sending alerts when rain is detected.
  • Automotive: Used in rain-sensing windshield wipers and other vehicle automation systems.
  • Industrial Applications: Monitor rain exposure on outdoor equipment and machinery to trigger protective measures.

How to Use:

  1. Connection:
    • Connect the VCC pin to a 3.3V or 5V power supply.
    • Connect the GND pin to the ground.
    • Connect the D0 pin to a digital input pin on your microcontroller to read the digital rain detection signal.
    • Connect the A0 pin to an analog input pin on your microcontroller to read the analog voltage corresponding to the amount of rain detected.
  2. Sensitivity Adjustment:
    • Use the potentiometer on the control board to adjust the sensitivity of the sensor. Turning the potentiometer will change the threshold at which the digital output changes state.
  3. Reading Data:
    • Read the digital output (D0) to get a binary indication of rain detection (1 for no rain, 0 for rain detected).
    • Read the analog output (A0) to get a continuous voltage level that varies with the amount of water on the sensing plate.

Package Includes:

  • 1 Piece-Rain Sensor Module
