@Them-Russians said in PIR-Sensor - put your mirror to sleep if not used:
@fox pop the plastic dome off and you’ll see the labeling. I believe the middle pin is the digital output and the ground and 5V power are on the outside.
The sensor is labeled. But on which pin on the raspi? Have i missed something in the module how-to?
-
@fox You define the pin in the config.js file.
Make sure you sue the GPIO pin number, and not the generic pin number.
For instance, in the pin diagram the pin 1 down from the top left is GPIO pin 2, but regular pin 3. In the config file, you would define it a SensorPIN = 2.

Thank you very much. I understood.
Does someone control this with a timeout? Or when switches the script the HDMI Port off? Perhaps some want x minutes to be shown?Edit. I am a noob. I just have to adjust the delay knob on the PIR-Sensor PCB :)

Love this Module, thanks.
I’m a noob and looking for some assistance to add a delay to turn off the display. Ideally the display would turn off 30 seconds after the last detected movement. Any help would be greatly appreciated.

I originally wasn’t going to use this module, but it seems pretty cool, so I’ll try. I, however, have no clue how to physically connect the raspberry pi to the PIR sensor without a breadboard. I understand that I must specify the GPIO pins I connect to in the config file, but that will only help me if I figure out how to connect everything (soldering?). Could someone help me? I’m completely new to motion detection. :dizzy_face:

@AAPS
(Raspi 3)
Just connect the PIR sensor Pins with three of these connector cables (female on both sides) directly to the GPIO pins on the PI, without soldering.
You need to know the pin assignments of your PIR sensor. I used:
(4) +5V
(6) GND (ground)
(32) GPIO12
i think you can also use (15) instead of my (32) then you don’t need to change the pin in the config file.
Hope that helps.

@Morningstar Thanks! Where could I buy everything? Amazon?
-
@AAPS
Yes, Amazon, ebay, electronic stores in your city. And there are dozens of online shops for raspberry, arduino and all kinds of add-ons. -
Is this the right cable to use? https://www.amazon.com/Icstation-Female-Jumper-Cable-Connector/dp/B01F59QFMM/ref=sr_1_2? ie=UTF8&qid=1486697807&sr=8-2&keywords=female+to+female+Rainbow+%2F+DuPont+Wire

@AAPS
Yes that’s the right one. -
Is it possible to switch the monitor on and off with the PIR? I would like to hide the sensor and turn on the monitor with a hand movement and then switch it off again with a new hand movement. The sensor should be hidden so that it registers only this hand movement and no other movements in the room. If the manual movement for switching off is once forgotten, the monitor should turn itself off after 30 minutes, for example.
Is this possible?
-
@Goldjunge_Chriz you might want to use the gesture module of mochman for it
-
Does it work well? I thought that with the PIR could be easier since I do not need any special gesture, only some individual movement.

Hello,
1st off I’m a total noob at coding so please forgive me. I have been able to set up my mirror and get several modules up and running. However, I am having quite a bit of difficulty with the PIR-Sensor. I have it wired directly to the GPIO(pins 2, 6, 15). I installed the MMM-PIR-Sensor via paviros instruction. At first I got the white screen. Somehow that issue is gone. Now I can’t get the module to work. I know the PIR sensor is working, because I am able to run a python script to detect motion. The script just keeps in running though even when I walk away from the sensor. Maybe the sensor is faulty?Any help would be greatly appreciated.
Thanks in advance

Hey Dirk, i was having some issues and was using “/opt/vc/bin/tvservice -o” and “/opt/vc/bin/tvservice --preferred && sudo chvt 6 && sudo chat 2” to turn my screen on and off as that seems to be what everyone is using. This worked reliably since i started using the PIR sensor.
All of a sudden this started making my screen go white when it issued the monitor on command…and the screen would stay white for a few minutes and sometimes it would come back.
Using your “vcgencmd” commands in place of the previous in my monitor on/off scripts everything is back to working again.
I had a couple questions. Firstly i didnt understand what you mean by hdmi_blanking=1…what does this do/should i put this in my boot/config.txt?? And secondly what is the difference between the two ways of toggling the monitor?
(I did ask my question here: https://forum.magicmirror.builders/topic/1780/white-screen-after-screen-resumes-from-pir-or-sometimes-randomly-can-still-access-via-ssh-requires-restart-sometimes/4 incase but stumbled upon this after.)

Hi!
NOOB alert!!
I have added the module, updated the config.js file accordingly, but then, with nothing connected, the screen turns completely white?? (Opposite to what I expect to happen).
Could you kindly indicate what I might observe when it is running as expected? With a PIR connected, and without?
I have learnt how to run “npm start dev”; What should I look for in that console if it is functioning?
Or any other means of testing if it’s working, or where it is breaking?
Much obliged!!

@Bangee Thanks for the assistance. I tried that link along with a couple of other suggestions that I came across from the forums but nothing worked. I went and ordered a new PIR sensor as a last resort and bam worked once I plugged it in. This is a great module. Its really going to save me some money in energy costs and increase the life of my MagicMirror Monitor.

I don’t yet have my PIR sensor (soon!), but had a question.
When the mirror is unused, with the monitor off, it doesn’t make sense to do frequent updates on all of the modules. I could tune those way back, if I could force a refresh on all modules when the PIR triggers a monitor wake-up.Is there an easy way to trigger a refresh of some/all modules when the PIR module senses a wake-up event?
