 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. See [PIN Restrictions](Peripherals.md#restrictions) on which pins not to use

+Alternatively, a PIR motion sensor can be configured as a switch with its state reported for autodiscovery by HomeAssistant.

+To have switches discovered SwitchTopic must be set to a custom name. And the [switch mode](https://tasmota.github.io/docs/Buttons-and-Switches/#switchmode) should be set to follow.

 ## AM312 
 
 [AM312](http://www.image.micros.com.pl/_dane_techniczne_auto/cz%20am312.pdf) works even on 3.3v instead of 5v (like HC-SR501) which makes it perfect for ESP8266 devices without a 5V line (like Sonoff Basic). It is also less prone to false triggers due to Wi-Fi interference.
