PIR sensor behind glass?
-
I used some cardboard and then made a little housing for my PIR under the bottom of the mirror. It is a little ugly, but hey this whole project for me was to make something cool (not necessarily beautiful)!
I did a few layers of cardboard between the sensor and the front to limit the viewing angles and for my needs it is perfect :)

@dmcinnes Would you mind share some code? :)

@Cato just the regular PIR sensor mirror code works fine! The data pin triggers in the same way as a PIR sensor.

hmm… some questions if you would not mind.
Ive just ordered 2 sensors .
I need to know what plugs in to what to feed in to the chips (im guessing the sensors i need? please explain what i am missing… and what connects in to the Raspberry PI.
Also note the second i want to have outside the home and set up to a facial recog module, and comand it to open the door via face and voice confirm if possibl.
And how this connects to the a

If you want a very simple solution (independent of MM completely), check out this script. This is what I am using, it is a very simple python script that reads the value of a PIR and then selectively turns on / off the monitor. You will need to change things up a bit as I wrote it for a C.H.I.P. but the GPIO library is the same.

@wjdw87 cool! The connection is basicly the same as a PIR sensor. It has three wires, ground, vcc, and data which goes high when it senses motion. I plugged it into the PI’s 3.3v, ground and I believe gpio 22 (whichever is the default for the module).
Since the wire comes out as a three pin JST I split it into individual header connectors because all the pins are not next to one another on the PI.Hope that helps!

Can anyone of you please share a picture of how you’ve connected the microwave sensor to the Pi pins?
I know this sounds dumb, but I can’t seem to find out what pin connects to what, as I don’t know what pin is ground and what pins is (data) out…Thanks!

VERY good choice! Mine also works independent… but I really like your idea!

@cowboysdude I recently picked up these microwave sensor modules to use in conjunction with the code you posted for PIR Sensor. I’m pretty new to all this, and I can’t get any function out of the sensor. Do you have some advice on how to troubleshoot this? It could be an error on my part in implementing the code, wiring it incorrectly, or something else, but I’m just not sure how to figure out what the issue is.
