Fingerprint Door Lock System Using Arduino Code

In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking.

Fingerprint door lock system using arduino code. First of all connect the fingerprint sensor to the arduino uno. Also it is almost impossible to trick this door lock since a fingerprint is difficult to copy so with a metal case instead of plastic this would be a very secure door lock. So a digital code lock can secure your home or locker easily. After downloading the sketch enrollto crowduino open the serial monitor and set the baud rate to 38400 you will see the outputs from the serial monitor to.

The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display. 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. 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. It will open your door only when the right password is entered.

It is also faster to use than typing the code of the keypad door lock. Glue or anything that can be used to fix these modules 5. Crowduino this is an arduino compatible microcontroller boards i use it because it is cheap enough and has some upgrading on the design such as the reset button on the side. Finger print is considered one of the safest key to lock.

Now i need to store my fingerprint to crowduino to let it open the door as i press the fingerprint. In this project we will learn how to make password based door lock security system using arduino 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. A servo with enough torque.

The project arduino fingerprint sensor lock is simply fabricated around arduino board. 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. Open the arduino ide open the file sketchbook enroll you will see the enroll code that function as a fingerprint registration. Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock.

Arduino fingerprint door lock with keypad and lcd. Now we have a functioning core of a system. Just place the finger and open the door. 5v usb power supply or 9v dc jack power supply.

This is a security door lock with fingerprint sensor. Introductionthe fingerprint door lock as the name suggests is an electronic door lock that can be installed on almost any access point in your house. It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. I use the following modules.
