Wemos D1 Mini and AM312 PIR Motion Sensor - seurat-atreides/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.
Learn more about PIR Motion Sensors.
The AM312 is pretty much the same as HC-SR505 but works on 3.3v instead of 5v.
