Biometric Based Door Lock System with Buzzer

Security has always been an issue of concern in every family and also in workplaces, shops, etc. Everyone is concerned about strangers walking into their house or workplace without their knowledge. The issue with the usual door lock is that it might potentially be opened by someone using a duplicate key. An alternative to this strategy is to employ a lock's password or pattern, which runs the risk of being discovered and allowing the lock to be opened. Therefore, integrating a door lock with biometrics can be a solution to these problems. In this project, we create a fingerprint-based door lock system that unlocks doors. This study focuses on creating a buzzer based biometric door lock system that eliminates the need for carrying around keys, preventing problems like key loss. When an unauthorized person tries to enter, the buzzer helps the owner be informed.
