MMM-PIR-Sensor tuning
-
@jc21 just for closure here I found the issue. After running the python script again I realised that the PIR was always HIGH even with the sensitivty dialled right down.
So I checked the leads going into the pi and found that, despite checking it many times, I’d mixed up GND and VCC :(
The lesson for any other idiots out there when testing is, run this Python script and make sure that the PIR stops broadcasting “Motion Detected!” when you cover it with something:
from gpiozero import MotionSensor import os pir= MotionSensor(22) //the gpio pin PIR OUT is connected to while True: if pir.motion_detected: print (“Motion Detected!”)
Code from this site
With some further adjustments for sensitivity it’s now working great!
-
Great stuff. People shouldn’t discount a faulty PIR either. The one I had on the shelf for ages wasn’t detecting quite right so I ordered another one and the difference in detection is huge. I’m not sure if these have a shelf life or what but yeah, that was my recent experience.

Hi all,
i have an issue with the PIR Sensor. I get alltime this error:

Can anybody help me?

- please run
npm list
and find out your version number of electron - change into the MMM-PIR-Sensor folder
cd ~/MagicMirror/modules/MMM-PIR-Sensor
- run
npm rebuild --runtime=electron --target=ELECTRONVERSION --disturl=https://atom.io/download/atom-shell --abi=50
and replace ELECTRONVERSION with the version number you found in step 1
- please run
-
@yawns. Is it possible that my Version is 1.4.13?
-
Yes, that is possible. When I had to run this command last time I was using 1.4.0 …
Just give it a try. Worst case is you have to delete the MMM-PIR-Sensor folder and git clone it again. -
@yawns now i get this error

why are you running it with sudo??
-
without sudo i get the same error

After a few New Installations now the mm starts and the PIR works.
