Fingerprint Door Unlock System Project

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.

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. 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. 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. A working video and complete code are.

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. This project includes a smart and affordable door lock enhanced with a fingerprint interface. For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module.

This is how you can use your smart phone s fingerprint sensor to control a door lock. In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking. 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. 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.

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. The project arduino fingerprint sensor lock is simply fabricated around arduino board. This system can prove very useful in housing buildings large offices universities and so on. If the fingerprint is authentic then it will open the door else the door will remain in a locked position.
