Automated Hybrid Smart Door Control System

This research paper successfully designed, developed and implemented an automated hybrid smart door control system which has the ability to secure a home up to 92% electronically. This smart door system is designed and implemented by building a hardware made up of the Bluetooth module and fingerprint scanner which are interfaced with the Microcontroller system that uses +5V power supply. The written programs were interfaced into the microcontroller chips by plugging the Arduino USB cable into the laptop and upload the codes. The microcontroller chips helped in enrolling the users fingerprint into the fingerprint scanner and it automatically administers and saves the users fingerprint after enrollment. Furthermore, after all the processes the user places the enrolled or registered finger into the fingerprint scanner which either accepts or denies the user by triggering the solenoid lock to either unlock, lock or deny access. This process of unlocking and locking requires using Bluetooth and fingerprint to either lock or unlock the door smartly without stress and it can be done within one second that is why the Solenoid lock is used in building this security system. This automated hybrid smart door control system developed has curbed the problem of door breaking theft for about 92%, strengthened security and as well made it so easy for the physically challenged people to have access to their homes without third party assistance
