UPDATE: Replaced my PIR-Sensor with a Doppler Microwave Sensor.

Yes, i’ve built two mirrors and now working on my third bathroom mirror and with x number of files open in Notepad++ it’s getting messy…and even if you can see the file name and it’s location (host name) you end up editing elsewhere :dizzy_face:

What type of mirror glass do you all have?

I have a Pilkington Mirropane Chrome Spy and to me it seems that this type of Mirror glass interferes with the RCWL-0516.

When doing tests (mirror glass taken off) the sensor works as expected but as soon as I put the mirror glass back it stops working through the glass.
Waving my hand at the side still works.

@devmil I have the same mirror, but 4mm thick, and it works really well. Thickness shouldn’t be an issue, because the sensor is easily able to detect motions in adjacent rooms separated by stone walls. I‘d suggest to increase slightly the sensitivity by increasing the trimmer value.

Further check the soldering joints between trimmer and sensor. Maybe they need to be reworked so that the solder provides a proper connection.

@devmil Hi Michael, i’ve been testing with d-c-fix mirror-effect privacy film and acrylic oneway mirror and both is interfering the PIR sensor so i had to put in a small box above the frame. Not a fancy design though…
For the acrylic i have spare place beneath the screen so i drilled a hole.
For the upcoming bath mirror i’ve ordered a Pilkington MirrorView. Don’t know yet if it will work with the sensor behind that glass though…otherwise i’ll put in a separate place/box. Hard to drill the glass and wouldn’t dare trying :-|

This is just amazing and pity I didn’t see it before I went into PIR usage.
If I put aluminum insulation on one side of sensor, can anyone confirm this can be used as 180-degree use?

@uros76 the detection range will very likely be more than 180 degree, as the emission characteristic is more or less spherical. Further, the detection range depends also on the layout of your rooms, walls etc. Just give it a try and see what the result is.

@bachoo786 I have discovered that in the newer versions of the operating software for the PI that my scripts do NOT work any longer as the commands to turn the monitor on and off have changed… I have as of yet to find the correct command lines to make it work. I tested for 3 days and couldn’t get it to turn back on… It’s not MM…

@cowboysdude scripts works fine with my pi3.

It seems pi4 has different way of putting a monitor to sleep, I never figured out how to do it on pi4.
Instead, I tested lubuntu on pi4 and managed to put it out of sleep with this mouse click script linked to PIR motion:

xdotool click 1

I can share more details on lubuntu setup if needed.

Yes it works great on a Pi3… :) I am still using it for that…

Yes please… I’d like to update the script for Pi4 but haven’t been able to get it working…
Thank you!
