      @lavolp3 Ah…now I got you.
      There are two options to reduce the sensor range:
      Option 1: The aluminum taped “Magic Box” like described here.
      Option 2: Replacing a resistor on the sensor to reduce the sensor range.

      I haven’t yet tried option2, as I’m waiting for some parts to do it. As soon as I got them I’ll test that option and will give feedback. For the time beeing, I just can make a statement for option 1, which requires no additional resistor.

      Maybe there is also an option 3, a combination of option 1 and 2…we’ll see.

        Excellent description. I like your innovation. I’m guessing this is going to replace the PIR sensor. I think most people have the same feeling as you about the appearance of the PIR. It does distract from the “magic”. Well done! :thumbsup:

        That would be the idea…easier to ‘hide’… the PIR is nice but ugly.

          Thank you so much for this…ordering one so I can get rid of the ugly PIR in my bathroom!!!
          Awesome job!!

            @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?

                  Thanks!

                    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

                        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.
