Fingerprint Door Unlock System Project

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.

Fingerprint door unlock system project.

In the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on. This system can prove very useful in housing buildings large offices universities and so on. 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. 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.

Therefore i installed an optical fingerprint sensor on the outside of the door that can also toggle the locked versus unlocked position of the servo. In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking. 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. For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module.

The project arduino fingerprint sensor lock is simply fabricated around arduino board. 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.

It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. Arduino fingerprint door lock with keypad and lcd. Now we have a functioning core of a system.
