Motion detection: PIR sensor vs picamera

ZombieDE

Hey,
I am currently looking for a way to turn my magic mirror on/off depending on when somebody is close to it.
Does anyone have experience with a PIR sensor, the picamera or any other hardware I could use?

@ZombieDE I used a Picamera in my first mirror. I wrote a tutorial on how to get it set up in the tutorials section. Check it out.

@bhepler Which picamera did you use? The normal or the NoIR version?

bhepler

@ZombieDE NoIR.

@ZombieDE I went the PIR sensor route, but note that it does NOT work from behind the glass. It needs to be exposed to work, which sort of sucks (and is something I should have researched beforehand).

And what do you recommend?

I have a broad frame and a quite small PIR sensor (this one, pictures of mirror here).

Currently it’ hanging behind the frame and is seeable, but I want to 3D-print a small mount, to screw it to the frame, so it’s not visible and measure IR in the area of your feet when you pass the mirror

So it’s possible to use a PIR sensor which is not visible directly when you have a broad frame
