MMM-PIR

MMM-PIR is a module for the MagicMirror project by Michael Teeuw.

It uses a PIR sensor attached to your raspberry pi's GPIO pins to check for users. After a configurated time without any user interaction the display will turn off. You can specify additional scripts (sh, python and js are supported) that will run after the timeout.

Configuration

To display the module insert it in the config.js file. Here is an example:

{
    module: 'MMM-PIR',
    position: 'bottom_center',
    config: {
        sensorPin: 4,
        delay: 10000,
        turnOffDisplay: true,
        showCountdown: true,
        callbackScripts: ["callback.py"]
    }
}

Option	Description	Type	Default
sensorPin	BCM-number of the pin	Integer	4
delay	time before the mirror turns off the display if no user activity is detected. (in ms)	Integer	10000 (10 seconds)
turnOffDisplay	Should the display turn off after timeout?	Boolean	true
showCountdown	Should the MagicMirror display the countdown on screen?	Boolean	true
callbackScripts	Scripts that execute after the timeout. Scripts must be placed inside the callbackScripts folder. Supported script types: sh, py, js	Array of strings	none

Note: The callback scripts to switch the screen on and off feature two ways of disabling the video output to the monitor. By default, this module uses vcgencmd. The second option (tvservice) can be used by removing the vcgencmd command and include the commented tvservicecommand in each file.
