The Access Control System will do its Ideal Routine which is monitoring the room's temperature and sending it to the remote PC via the USART protocol.
When the system gets interrupted, the system will ask the user to enter the Common PIN and the Personal PIN using the Keypad.
Then the system will check the PINs. If they are correct, the system would then start unlocking the door.
If any of the PINs is wrong, the user will get a second chance to enter the correct PIN. And if the user entered any PIN wrong twice, the system would become inactive and remain inactive for 30 seconds.
