Fingerprint Door Unlock System Project

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 door unlock system project.

A working video and complete code are. In this tutorial i m going to show you how to build a door lock that uses a fingerprint sensor and an arduino uno. For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module. 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 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. 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 the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on. In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking.

This is how you can use your smart phone s fingerprint sensor to control a door lock. This project includes a smart and affordable door lock enhanced with a fingerprint interface. 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. After that touch the fingerprint button and it will ask you to scan your finger on the fingerprint sensor.

Now we have a functioning core of a system. Because it offers the flexibility to add more features to the system. 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. If the fingerprint is authentic then it will open the door else the door will remain in a locked position.
