Independent display controller based on PIR sensor.

@Beh Thx for sharing! One question : what are the physical settings to apply to the sensor itself pls? (Jumper & the 2 knobs)

[Beh]

Example configurations for wiring are shown here:

and here:

I can’t really tell you the jumper and knob configurations, because I’m using a simple sensor like this:

Maybe you look in the PIR HOWTO thread or ask a question there:

@Beh i see thx! maybe it’s better to use your one to somehow bypass these settings which are a bit frustrating. i did’t really get the systemd option (i am new) but as i understood it’s like a crontab, correct?

[Beh]

@bibi No, it’s more like having it added to the autostart (like on windows). Then it’s running as a service in the background, which can be controlled via systemd’s systemctl command.

hi @Beh ! unfortunately your module is not working for me :( could you please help me to figure out why? i have bought the same PIR sensor and plug it in the gpio 14 (physical pin 8) thx!

[bibi]

it’s solved ;-) thx anyway

[bibi]

@beh hi! i was wondering if there was an easy way to add a fading effect when the mirror goes to sleep and wake up? would be interesting in this as well? thx

[Beh]

Hi @bibi, I hope, I understand that right.

I don’t think that this is very easy. Because the script just turns the HDMI port of the RaspberryPi to on and off. So a fading effect wouldn’t be quite easy I think

[bibi]

@Beh i understand this. No problem and thx for reply! :)

@bibi hi can anyone help me with screenshots the file path where to enter the below commands to start it at boot time

cp ./pir_sensor.service /lib/systemd/system

systemctl daemon-reload

systemctl start pir_sensor.service
