Smart Door Lock System With Fingerprint Using Arduino

The aim is to control a door lock without keys but using a smart phone instead.

Smart door lock system with fingerprint using arduino.

Now we have a functioning core of a system. Make sure you get a fingerprint sensor that works with the arduino through the serial communication. First of all connect the fingerprint sensor to the arduino uno. Finger print is considered one of the safest key to lock.

The project arduino fingerprint sensor lock is simply fabricated around arduino board. Connections for this project are very simple. 4 to 8 working days from the date of purchase. 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.

Fingerprint door lock system using arduino and smart phone. Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock. This project includes a smart and affordable door lock enhanced with a fingerprint interface. Rampiot cool smart lock.

In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking. For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module. The circuit diagram for fingerprint door lock using arduino is given below. 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.

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. This is a security door lock with fingerprint sensor. 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. The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display.

This smart lock allows create rules and scheduled actions with your voice using alexa and a new unlock feature using smartphone fingerprint. Rfid and keypad door lock and alert system using arduino. The input pin of the relay is connected to the pin 9 of.
