The M5Stack PIR Motion Sensor (AS312) 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. Delay (high during the period and allow repeated triggers) until the trigger signal disappears (restores low).
