In this project we are going to build a biometric lock using arduino nano with bluetooth module solenoid lock and android phone.
Fingerprint door lock system project.
In the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on.
Every key has double features.
In this arduino fingerprint sensor project we have used fingerprint sensor module to take finger or thumb impression as input in the system.
The project arduino fingerprint sensor lock is simply fabricated around arduino board.
Apart from hardware a mobile application is also used to scan and verify the fingerprint and send.
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.
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.
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.
They are incredibly unique and it is very hard to copy them or fake them or alter them.
In this tutorial i m going to show you how to build a door lock that uses a fingerprint sensor and an arduino uno.
Creating a fingerprint door lock system.
Enroll key is used for enrolling new finger impression into the system and back function as well.
