Fingerprint Door Lock System Project

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.

Fingerprint door lock system project.

Risk and limitation of fingerprint door lock system. Every key has double features. 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. Enroll key is used for enrolling new finger impression into the system and back function as well.

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. There are many iot controlled locks are available like web controlled door lock face recognition door lock etc. In the future there could be many more applications like fingerprint based driving licences bank accounts operation 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.

In this project we are going to build a biometric lock using arduino nano with bluetooth module solenoid lock and android phone. They are incredibly unique and it is very hard to copy them or fake them or alter them. Apart from hardware a mobile application is also used to scan and verify the fingerprint and send. In this arduino fingerprint sensor project we have used fingerprint sensor module to take finger or thumb impression as input in the system.

In this tutorial i m going to show you how to build a door lock that uses a fingerprint sensor and an arduino uno.
