Fingerprint Door Lock 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 lock system project.

Here we are using 4 push buttons to enroll back delete ok up and down. Enroll key is used for enrolling new finger impression into the system and back function as well. Risk and limitation of fingerprint door lock system. Arduino fingerprint door lock with keypad and lcd.

It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. They are incredibly unique and it is very hard to copy them or fake them or alter them. 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. It is mostly based upon a system that gives authorization based on an individual s fingerprints as fingerprints cannot be similar to 2 or more individuals.

After learning arduino for 2 weeks i decided to diy a fingerprint lock with arduino. A fingerprint lock would be help for me and there are plenty of these kinds of locks on the market as the picture above. In the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on. 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.

Every key has double features. In this tutorial i m going to show you how to build a door lock that uses a fingerprint sensor and an arduino uno. In this arduino fingerprint sensor project we have used fingerprint sensor module to take finger or thumb impression as input in 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.

The project arduino fingerprint sensor lock is simply fabricated around arduino board. Now we have a functioning core of a system. Creating a fingerprint door lock system. 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.
