A door that is not completely opened or stays open for to long triggers an alarm.
When the roller door was lowered the arduino would enter the door in transition state again and stay that way until the door closed and the bottom sensor was triggered.
Please note that this item not fit to iron door it will decline magnetic of the sensor.

Mc 38 wired door window sensor magnetic switch home alarm system detector.
I mounted the 2 switches at each end of the garage door rail.
Alarms are sent by sms.
On the lcd screen you can see the last movements of your doors.
The arduino would now enter a door closed indicator state and leave the led on for 10 seconds before entering the door closed sleep state.
When a door opens or closes the movements are logged.
