Fingerprint Door Unlock System Project

Arduino fingerprint door lock with keypad and lcd.

Fingerprint door unlock system project.

Introductionthe fingerprint door lock as the name suggests is an electronic door lock that can be installed on almost any access point in your house. In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking. Because it offers the flexibility to add more features to the system. This simple fingerprint door unlock project using arduino can be very useful for door security forensics crime investigation personal identification attendance system and much more.

This door lock will only open the door when the user scans the right fingerprint that is recorded on the system but the door will remained close upon entering the wrong fingerprint. Fingerprint based door lock our proposed fingerprint based lock system is a reliable and very secure lock that will not only ensure safer environment but also ease lifestyle. In this tutorial i m going to show you how to build a door lock that uses a fingerprint sensor and an arduino uno. To enhance the system i ve also installed a small oled display on the outside of the door to show the system s status i e.

Now we have a functioning core of a system. Finger print is considered one of the safest key to lock or unlock any system as it can recognize any person uniquely and can t be copied easily. The project arduino fingerprint sensor lock is simply fabricated around arduino board. In the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on.

It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. Not only to ensure door security this project also make certain to assist in fields like forensics crime investigation personal identification attendance system and there is a lot more. For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module.
