Read the statement by Michael Teeuw here.
Do you use a PIR sensor? How do you hide it?
-
The microwave sensor is compatible with the MMM-PIR-sensor module.

@onkelbobby It works through 20mm of wood for $3.59!? This seems too good to be true! I ordered one. Might be a week or two before I have a chance to test it out. …Actually shipping on that item is super slow (about a month). Still, I’m holding off on drilling the PIR hole until I can try it out the RWCL-0516.
Edit - Found it here for $1. Shipping times are still brutal though unless you pay about $30 for air mail. btw dimensions of the little fella are 35.9 X 17.3mm/1.41 X 0.68inch

I could use mine because it worked through the prick wall behind the mirror.
-
Hide it? Why it goes in it’s own enclosure of course? :)

@htilburgs
mine is connected to an Arduino micro 3.3V version and this one is controlling a simple relais switching the monitor inside the mirror. But as @MadScientist already mentioned you can also hook it up to the Raspberry Pi since It works perfectly with MMM-PIR-Sensor. -
Yeah, that’s my understanding. I can’t find the post but it was here on this site. A guy did some experiments to find the smallest size hole his PIR sensor actually required. He tried 1mm, 2mm and 4mm(?). He said it worked just fine with a 2mm hole.

Hi, I’ve been busy with this problem for a long time until I found the solution. And it’s called RCWL-0516 Microwave Radar Sensor. Guys, forget PIR sensor, the RCWL-0516 you can completely obstruct in the frame behind the mirror. It works perfectly with paviro / MMM PIR sensor. You get 5 pieces for 8 € on Amazon. I hope I could help you. And forgive me my bad English. Regards
