UPDATE: Replaced my PIR-Sensor with a Doppler Microwave Sensor.
RCWL-0516 microwave sensor
Thank you so much for this…ordering one so I can get rid of the ugly PIR in my bathroom!!!
@cowboysdude Thanks! I’m looking forward to your experiences with the sensor!
I’ll try this out hopefully tonight but not with an Aluminium tape but with aluminum foil. Should work as well as far as I can see.
@lavolp3 yes, should do equally. I had some leftover of the tape and it was more convenient to apply. I found some post from you a few months ago, when you struggled to make the sensor work. I hope you get some better results now.
@Fozi Is there a wiring diagram for this? I know where the wires on my pi are and there two wires running to the sensor but where are they connected on the actual sensor?
You only use Vin (5V), Vout and GND. CDS (for applying a photo diode) and 3V3 (delivers 3.3V output) remain unused. For Vout you can use also oher GPIO pins (labeled “Digital I/O” in the 2nd diagram), in case GPIO_4 is already used.
The ferrite bead is optional. It is a left over from the PIR sensor I had attached. If you may need one, you can dismantle an old VGA cable and use that one.
Here the wireing diagram:
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
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 !!!
