<![CDATA[Problem with my pir sensor]]>Hi

I have a pir installed but unfortunately the screen never goes into standby,

The module MMMpirSsensor is nevertheless well installed I use the output gpio 22
If it comes from the pir or elsewhere?
thank you in advance

I tested my pir with my multimetre I just disconnected the output and testing directly on the pine I saw that my output always remained high.
I changed my pir now all works perfectly

I was wondering if my PIR wasn’t broken but I wanted to check it before.

So before changing your PIR you can test it by a simple python script. I found this (in french) : http://mycoolpizza.blogspot.fr/2013/05/raspberry-pi-utiliser-un-capteur-de_29.html?m=1

thanks for your answering i put a ferrite bead near gpio connector but my output 15 gpio 22 is always high
so my screen is always turn on .
i don’t why …
Perhaps my pir is broken because the first time I plugged in I reversed the power supply…

Apparently, the PIR gets interference from the Wireless chip on the Raspberry Pi 3 and it causes it to give bad readings, even the Adafruit site has a note about it:

https://www.adafruit.com/product/189

“PIR sensors and the Raspberry Pi 3 sometimes don’t get along - if you’re having false trigger reports, make sure the PIR Sensor is far away from the Pi 3”

Here is another possible solution - this guy used some kind of interference blocker on the wire, check it out:
