Detect human body / motion with the PIR sensor

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 for a while.

The level stay HIGH (high during the period and allow repeated triggers) for a given time/delay until the trigger signal disappears. When the trigger signal disappears, the output signal does low.

This Unit communicates with the M5Core via the GROVE B.
