Detect motion from a PIR sensor and publish it to an MQTT broker. All in Node.js and running on an Onion Omega.

PIR settings for HC-SR501

Time delay (left screw with sensor pointing upwards): Fully counter-clockwise (3 sec)
Sensitivity (right screw with sensor pointing upwards) depends on use case: Fully clockwise for 3 meters, fully counter-clockwise for 7 meters

Copy mqtt-nodemotion.init_file to /etc/init.d/mqtt-nodemotion
Change PROJECT_DIR (and other settings) if needed
Do chmod +x /etc/init.d/mqtt-nodemotion to make it executable
Do /etc/init.d/mqtt-nodemotion enable to enable autostart on boot
Do /etc/init.d/mqtt-nodemotion start to start it for the first time
Do tail -f /var/log/mqtt-nodemotion.log and check for any errors. If you see nothing, wait a moment as nodejs takes some time to launch. When everything's good, the last line should read "Running...".
