PIR Motion Sensors - Tasmota

PIR Motion Sensors. PIR motion sensors, albeit called sensors, are configured as switches in Tasmota since they basically report motion ( 1) or no motion ( 0) to the device. Most PIR's are single wire and they require connecting to VCC, GND and one GPIO. In this guide we will use GPIO13 as the pin that the PIR output is connected to.
