M5Stack PIR Sensor Unit - AS312

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. Delay (high during the period and allow repeated triggers) until the trigger signal disappears (restores low).

This Unit communicates with the M5Core via GROVE B.

Note:

1. This unit is actually an add-on unit for M5Stack controllers. The controllers are NOT INCLUDED in the package. However, it is compatible with following controllers:
   • M5Stack Basic ESP32
   • M5Stack Fire ESP32
   • M5Stack ATOM Matrix ESP32
2. If you're interested to get other M5Stack modules and units in your hand for a lot more fun projects, you may get them here.
