  • Specification

    • Detection Method: Passive Infrared (PIR) technology
    • Detection Range: Varies depending on the model, typically around 5 to 12 meters (16 to 40 feet)
    • Detection Angle: Usually around 120 to 180 degrees
    • Sensitivity Adjustment: Allows fine-tuning of the sensor's sensitivity to motion
    • Time Delay Adjustment: Sets the duration the sensor remains active after detecting motion
    • Operating Voltage: Usually 3.3V to 5V DC
    • Output Type: Digital signal (typically high or low logic level)
    • Dimensions: Varies depending on the model


    • Power Supply: Connect the VCC pin of the PIR sensor to the positive supply voltage (3.3V to 5V) of your microcontroller or development board.

    • Ground: Connect the GND pin of the PIR sensor to the ground (0V) of your system.

    • Output Connection: Connect the OUT or SIGNAL pin of the PIR sensor to a digital input pin of your microcontroller or development board. This pin will receive the digital signal indicating motion detection.

    • Sensitivity and Delay Adjustments: If available, adjust the sensitivity and time delay settings on the PIR sensor according to your requirements. These adjustments can typically be made using potentiometers or DIP switches on the sensor module.

    • Power-Up Initialization: After connecting the sensor, give it a few seconds to stabilize during power-up before reading the output signal.

    • Reading the Output: In your microcontroller code, read the state of the digital input pin connected to the OUT or SIGNAL pin of the PIR sensor. A high or low logic level will indicate the presence or absence of motion, respectively.
