Wemos D1 Mini and AM312 PIR Motion Sensor - RTurala/Sonoff-Tasmota GitHub Wiki

AM312 PIR Motion Sensor (single pin)

PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. See PIR Motion Sensor for more information.

The AM312 is pretty much the same as HC-SR505 but works on 3.3v instead of 5v.
