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

Super Awesome yet again!! Thank you! I don’t use the PIR module… I have a Python script I run behind everything. It works very well for me but this will work so nice, and now I can move it behind the glass!

Now if I can just remember where I put my ferrite beads… I know I have some … but where LOL

Hi folks,

sooner than expected I modified the sensor with a trimmer resistor.
For that I also updated my initial post and enhanced the tutorial, where now both options are described. Enjoy and give me your feedback, how that works for you.

@Fozi nice update… very clear and helpful

Once again excellent work! I love the trimmer it’s a great idea for those with limited space!
For some strange reason I have left a gap at the top of my mirror that fits what I build perfectly!
I wanted a bigger mirror so I bought the glass oversized and centered the monitor in it :)

This, accidently, left me enough room to fit this in perfectly!

So what I did was design a “T” with a whole in it to mount the sensor and install it inside the box.
I am a contractor so having aluminum tape was not a hard thing for me to come up with.

Thank you @Fozi for this entire project! Allows me to get rid of the ugly PIR sensor outside the mirror and place a sensor behind the scenes but works as intended.

So for me option 1 works great! This won’t work for everyone but in my case perfect!
[Have NOT installed it in the mirror yet but will today]

Here’s the pictures.

Once again, Thank you @Fozi !!!

Dude, (can I call you dude?) although I don’t use a sensor (I have a cam on my first mirror w/Pi) I appreciate what you’ve done here. I’ll say it again (in different words), I think this is the death knell of the PIR sensor. So, thanks. :thumbsup:

Peace!

@cowboysdude I‘m totally happy that I cold help and to receive so positive feedback! I love it when a plan works!😁 Thanks!
This T-shaped holder, is it 3D-printed or an off-the-shelf available part? It‘s totally cool!

Sure, call me Dude, if you like😁

Let‘s get the warts outta here!🤣 and thanks for the overwhelming feedback!

Ok so here’s my final and it’s working perfectly! I tried it in various spots.

Thanks to @Fozi again…now there’s a very complete forum topic that anyone can follow!!

I added 2 additional layers of aluminum tape… there are no untaped spaces on the box anywhere… then moved it to the back of the cabinet and now you have to walk up to it to make it come on… PERFECT!! :)

I tried behind the glass… too sensitive
I tried taped to the back of the monitor … too sensitive.
Moved to the back of the cabinet which makes it about 4" away from the glass… BINGO!!

[PS… don’t mind my ugly wiring LOL]

@cowboysdude Great News, excellent!👍🏻

@cowboysdude
am I seeing it right that also the side of the case looking at you is aluminium taped?
So the whole case is taped in your case?
