PIR sensor behind glass?
-
@RedNax Alright, is that the case with all types of glasses? I guess it would be?
-
@yo-less It think all mirrors suffer from this… You need enough brightness to show things in the day… Which will be overkill at night…
-
@RedNax Apparently some monitors seem to allow for external commands to change the light levels:

@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!
