Pir sensor wiring for nodemcu esp32

[primeroz]

I have a kincony pir sensor but still waiting to receive the A4 board so in the meantime I was thinking to wire it to a nodemcu esp32. 

Looking at the wiring diagram https://www.kincony.com/how-to-use-pir-sensor.html


How should I wire the signal and COM to a nodemcu ? 

Is the signal just a 3.3v so I can just connect it to any gpio ?
What about the COM ?

Thanks
