Smart Door Lock System With Fingerprint Using Arduino

The input pin of the relay is connected to the pin 9 of.

Smart door lock system with fingerprint using arduino.

This is a security door lock with fingerprint sensor. 4 to 8 working days from the date of purchase. 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. Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock.

The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display. 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. Here we are only connecting a solenoid lock relay module and a bluetooth module with arduino nano. This project includes a smart and affordable door lock enhanced with a fingerprint interface.

For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module. In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking. 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. Make sure you get a fingerprint sensor that works with the arduino through the serial communication.

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. The aim is to control a door lock without keys but using a smart phone instead. Finger print is considered one of the safest key to lock. The project arduino fingerprint sensor lock is simply fabricated around arduino board.

This smart lock allows create rules and scheduled actions with your voice using alexa and a new unlock feature using smartphone fingerprint. First of all connect the fingerprint sensor to the arduino uno. Connections for this project are very simple. 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.

The circuit diagram for fingerprint door lock using arduino is given below. Now we have a functioning core of a system. Rfid and keypad door lock and alert system using arduino.
