PIR sensor behind glass?
-
@yo-less said in PIR sensor behind glass?:
Can a PIR sensor be covered by anything at all or does any kind of material automatically block motion detection?
You really can’t cover a PIR it just won’t work… BUT you can remove the ‘dome’ and incorporate into the frame a little better OR you can just put it into the frame with the ‘dome’ on it and make it decorative…

@yo-less changing the brightness would be really nice… having it automatic would be better… you know at a certain time of night it dims automatically… but there is this…

@cowboysdude Thanks for the link. Does f.lux have access to the monitor’s brightness settings? As this has nothing to do with my original question I will start a new topic concerning the brightness issue at night.

@cowboysdude We might just drill a tiny hole into the frame of the mirror and put the PIR behind it without its Fresnel cover. Will experiment with that idea some more.

That’s the approach I was thinking of. Which PIR will you use?

@yawns I’ve got the HC-SR501 / D-SUN RCW-0506 and it’s working as it should.
I paid €8 for two sensors and shipping to Germany. The one in use even survived my failed attempts at connecting it to the correct pins :). -
I just like the camera… it’s a personal choice :) But drilling a hole will work too!! I don’t see a thing wrong with that!

@cowboysdude I’m just not comfortable with the idea of a camera in my bathroom (or any other room, for that matter). Raspbian is a pretty open platform and I don’t want others to take control of any cameras I might have installed in my home. And it’s not like all sorts of people wouldn’t be interested in spying on other people.
Have started experimenting with the PIR sensor, it’s looking good so far, will let you guys know about my progress.

Another possibility: I ordered a couple of these $2 microwave radar motion detectors to see if they will work behind my glass. Still waiting to receive them though:

Wow, the microwave approach sounds good. Will this work behind the mirror?
