MH-SR602 Mini Motion Sensor Detector Module – PIR Infrared Sensor

The MH-SR602 is a compact pyroelectric infrared (PIR) motion sensor module designed to detect human body movement. With a sensing range of up to 5 meters, it's ideal for applications such as motion-activated lighting, security alarms, and presence detection systems.

Note:
The output high-level signal duration is factory-set to 2.5 seconds but can be adjusted from 2.5 seconds up to 1 hour by changing a specific chip resistor. Refer to the resistor value chart for typical delay time adjustments when modifying the module.
