Motion Detector

cpramhofer

could you please give me (and maybe others) the detailed instruction how these files look in detail and where those are located?

thanks a lot in advance,
Christoph

here is what i have done, actually it works - i will watch it a few days.

switch to /bin/

cd /
cd bin

open nano and create a shell script

sudo nano monitor_on.sh

write the “On” Command in it and save with Ctrl+x

/opt/vc/bin/tvservice --preferred && sudo chvt 6 && sudo chat 7

open nano and create another shell script

sudo nano monitor_off.sh

write the “Off” Command in it and save with Ctrl+x

/opt/vc/bin/tvservice -o

make both shell scripts executable

sudo chmod +x monitor_off.sh
sudo chmod +x monitor_on.sh

open the crontab and add the following at the end

switches the monitor off and on every 15 minutes. this is for experimenting, i will look how it works and will set the

time up as.

15 * * * * sudo /bin/monitor_off.sh
15 * * * * sudo /bin/monitor_on.sh
@reboot sudo modprobe bcm2835-vl2

Update:

https://github.com/cowboysdude/Pir-Sensor

Monitor was only partially coming back on this should fix that.

my monitor won’t turn back on
when I run “npm start dev”, it shows “compare result=Infinity,Infinity;0,0” , seems like it can’t capture any movement
the camera module works outside MagicMirror
when I tried “sudo modprobe bcm2835-v4l2”, it says “modprobe: invalid option – ‘4’”
how can I fix this

Hi @cowboysdude

thank you for your files and the explanation. what i don´t understand is how this all works together with the “Motion Detector” - i would prefere to use a camera instead of a PIR Sensor but as far as i see i have to install the pir.py file which is calling the on&off files and referring to the PIN with the connected PIR sensor.

is there a way to use the on&off files with the “Motion Detector” Module?

greets
Christoph

Hi guys

as it looks that it isn´t an MM problem but an Pi Problem…another try:

sudo nano /etc/kbd/config

change the values to zero

BLANK_TIME=0
POWERDOWN_TIME=0

good luck

@cpramhofer There is a module for camera control… cannot remember the name of it but look around here I KNOW there’s one here.
