In this project we have used a servo motor sg90 which acts as rotary access to door unlocking.
Fingerprint based security system and door lock circuit diagram.
Arduino fingerprint sensor lock.
Bank lockers or security safes.
Many of the banks use key based or password based locks for their lockers or safes.
Biometrics based security systems are far most secure and accurate than traditional password or token based security systems.
For example a password based security system has always the threat of being stolen and accessed by the unauthorized user.
In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking.
Now if a fingerprint is detected the system scans the fingerprint against stored ones.
12v power is the main source of energy supply required for this system which is given to the v in pin of arduino board.
Finger print is considered one of the safest key to lock.
I am not a professional so haven t used any editing software like fritz to edit the code.

We are implementing this bank locker security system using fingerprint password and gsm technology based security system which provide most.
It is based on atmega328 atmega328p and has 14 digital input output i o pins six analogue inputs 32k flash memory 16mhz crystal oscillator a usb connection power jack icsp header and reset button among others.
Light operated internal door latch.
In monitoring mode the system monitors for fingerprints.
1 3 1 accuracy and security.
If a match is found the system operates the motors to open the door for those users else the system does not open the door.
In our security system gsm plays important role.
Through the use of gsm the user will get the message if an unauthorized person will try to open the lock.
We have used 2 leds one as a green led and other the red led which acts as access granted and access denied indicator.
This door lock will only open the door when the user scans the right fingerprint that is recorded on the system but the door will remained close upon entering the wrong fingerprint.
Circuit diagram of the fingerprint door unlock system the brain of the circuit is arduino uno mcu board board1.
