M5Stack PIR Motion Sensor (AS312)

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.
