Here we are only connecting a solenoid lock relay module and a bluetooth module with arduino nano.
Smart door lock system with fingerprint using arduino.
This is a security door lock with fingerprint sensor.
Now we have a functioning core of a system.
First of all connect the fingerprint sensor to the arduino uno.
For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module.
Rfid and keypad door lock and alert system using arduino.
In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking.
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.
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.
Connections for this project are very simple.
Finger print is considered one of the safest key to lock.
The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display.
Fingerprint door lock system using arduino and smart phone.
Make sure you get a fingerprint sensor that works with the arduino through the serial communication.
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.
This project includes a smart and affordable door lock enhanced with a fingerprint interface.
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.
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.
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.
The project arduino fingerprint sensor lock is simply fabricated around arduino board.
Rampiot cool smart lock.
4 to 8 working days from the date of purchase.
