MHSR602 Mini Motion Sensor Detector Module SR602 Pyroelectric Infrared PIR Kit Sensory Switch for Arduino DIY with Lens What this module does This compact MHSR602 SR602 PIR motion sensor detects changes in infrared radiation caused by moving people or animals and produces a switchlike output that can trigger other electronics. The included lens focuses infrared signals onto the pyroelectric element so the module responds to motion reliably in typical indoor applications. Key benefits Ready for DIY and prototyping: Small footprint and simple wiring make the module easy to add to Arduino and other microcontroller projects. Practical motion switching: Produces a clear digital output to drive relays, LEDs, alarms, data loggers, or microcontroller inputs for automation tasks. Space efficient: Mini size fits into tight enclosures and compact builds where larger sensors would not be suitable. Lens included: Builtin lens improves detection sensitivity and coverage without extra parts. Versatile integration: Works well in hobby electronics, sensor kits, and prototype boards. Important attributes Function: Pyroelectric infrared motion detection with digital switch output. Compatibility: Designed for use with Arduino and other common microcontrollers and electronic control circuits. Size: Miniature module suitable for compact projects and enclosures. Material and construction: Sensor element plus lens mounted on a small PCB for straightforward mounting and connection. Performance: Provides reliable motion detection for typical indoor environments and simple automation tasks. Practical use scenarios Automatic lighting: Trigger corridor or stairway lights when motion is detected to improve convenience and save manual switching. Security and monitoring: Use the module to wake a camera, sound an alert, or start a recording when movement is detected near doors or windows. Interactive projects and robotics: Detect human presence to initiate responses in robots, displays, or interactive installations using Arduino or similar controllers. What you receive A compact MHSR602 SR602 PIR motion detector module with lens, suitable for Arduino DIY projects and general motiontriggered switching applications.
