microwave sensors (rcwl-0516)

Has anyone played with one of these?
They seem quite interesting, looks like they can see through walls.

The connection sensor-d1 mini seems easy, GND to GND, VIN to 5V, and OUT to D1. When a motion is detected, OUT sends a 3.3 voltage to d1 to trigger the gpio.
Wouldnt it be better to connect OUT to D4 which is the d1 mini's main LED?

There's no reason this shouldn't work as all it does is send a "high" or "low" signal to a pin on the mp board. I'm going to try to integrate
the rcwl-0516 with my esp32-cam code. My goal is to have the rcwl-0516 send a signal to the program when a person comes into view and trigger the esp32-cam to take a picture. Also, I want to send that picture to my ipad view sms or ifttt or maybe mqtt...
In essence I'm trying to build my own intrusion detection system with the boards I have on hand. I already have the esp32-cam working with micropython thanks to some work done by lemariva so it shouldn't be too difficult to get the rest working as well. As far as the rcwl-0516, it doesn't require any drivers to work, it's just a simple "on/off" signal device like a PIR sensor, so any programs using the PIR sensor and micropython or circuitpython should work fine with it.
