Arduino Fingerprint Door Lock Project

The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display.

Arduino fingerprint door lock project. Using a little arduino programming the fingerprint reader checks to see if you have access and if approved the arduino mega development board unlocks the door using a micro servomotor. Introduction of arduino fingerprint sensor lock. If the correct finger is placed the leds cheerfully light up green the door unlocks and the display welcomes you in. The project arduino fingerprint sensor lock is simply fabricated around arduino board.

Find these and other hardware projects on arduino project hub. It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door strike with a relay. In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking. Introduction the fingerprint door lock as the name suggests is an electronic door lock that can be installed on almost any access point in your house.

First of all connect the fingerprint sensor to the arduino uno. The default pins for serial communication on the arduino uno are pin 0 rxd and pin 1 txd of the board but we are going to use other pins for serial communication. Whether from the inside or outside whenever the door is locked the leds turn red and whenever the door is unlocked they turn green. Hello and welcome to this project actually it includes two projects but they re pretty much the same it s a door lock system based on an arduino uno board fpm10a optical fingerprint sensor and a lcd i c screen but for the other version we include a keypad.

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. From inside you can press the reset pin on the arduino to lock or unlock the door. This is a security door lock with fingerprint sensor.
