PIR SKU:U004 Description PIR is a human body infrared unit. It belongs to the "passive pyroelectric infrared detector". It detects the infrared radiation emitted and reflected by the human body or object. When infrared is detected, the output level is high and it takes a while.

Module pins: 5V, GND, SIG. Schematik maps them to your board in the app.
PIR and mmWave presence sensors, Hall-effect and angle encoders, piezo vibration discs, gesture breakouts and more — grouped here because they fit nowhere else.
