How To Create A Fingerprint Sensor Door Lock With An Arduino Uno Arduino Finger Print Sensor Door Lock System

First of all connect the fingerprint sensor to the arduino uno.

Smart door lock system with fingerprint using arduino.

Rfid and keypad door lock and alert system using arduino. 4 to 8 working days from the date of purchase. Rampiot cool smart lock. Finger print is considered one of the safest key to lock.

In this we used a fingerprint sensor to open the door lock and close the door lock with help of arduino uno only authorized person can open or close the door. This smart lock allows create rules and scheduled actions with your voice using alexa and a new unlock feature using smartphone fingerprint. This project includes a smart and affordable door lock enhanced with a fingerprint interface. This is a security door lock with fingerprint sensor.

The circuit diagram for fingerprint door lock using arduino is given below. Connections for this project are very simple. For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module. 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.

In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking. The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display. Now we have a functioning core of a system. The project arduino fingerprint sensor lock is simply fabricated around arduino board.

The aim is to control a door lock without keys but using a smart phone instead. 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. Make sure you get a fingerprint sensor that works with the arduino through the serial communication. 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 input pin of the relay is connected to the pin 9 of. 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. Here we are only connecting a solenoid lock relay module and a bluetooth module with arduino nano.
