Fingerprint Door Unlock System Project

This project includes a smart and affordable door lock enhanced with a fingerprint interface.

Fingerprint door unlock system project.

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. In this tutorial i m going to show you how to build a door lock that uses a fingerprint sensor and an arduino uno. 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 system can prove very useful in housing buildings large offices universities and so on.

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. If the fingerprint is authentic then it will open the door else the door will remain in a locked position. 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.

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. Because it offers the flexibility to add more features to the system. Now we have a functioning core of a system. In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking.

The project arduino fingerprint sensor lock is simply fabricated around arduino board. A working video and complete code are. After that touch the fingerprint button and it will ask you to scan your finger on the fingerprint sensor. In the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on.
