Fingerprint Door Lock System Project

Here we are using 4 push buttons to enroll back delete ok up and down.

Fingerprint door lock system project.

In this project we are going to build a biometric lock using arduino nano with bluetooth module solenoid lock and android phone. In the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on. The project arduino fingerprint sensor lock is simply fabricated around arduino board. Risk and limitation of fingerprint door lock system.

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. Apart from hardware a mobile application is also used to scan and verify the fingerprint and send. Every key has double features. 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.

They are incredibly unique and it is very hard to copy them or fake them or alter them. There are many iot controlled locks are available like web controlled door lock face recognition door lock etc. 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. In this arduino fingerprint sensor project we have used fingerprint sensor module to take finger or thumb impression as input in the system.

Enroll key is used for enrolling new finger impression into the system and back function as well.
