However thumbnail of every human being is unique so lock will not open unless the same person is present to give the impression of fingerprint.
Fingerprint based door lock system project report.
Because it offers the flexibility to add more features to the system.
This project includes a smart and affordable door lock enhanced with a fingerprint interface.
Standard door finger print scanner are explained fully in the third chapter of this project report.
Fingerprint based security system is the most secured system as compared to other systems.
It can be controlled through its serial port.
Reason is that rfid card or keys of lock can be stolen password may be leaked.
You can add a fingerprint delete a fingerprint and identify the fingerprint.
The micro controller at89s52 interacts with the module.
Circuit diagram of the fingerprint door unlock system the brain of the circuit is arduino uno mcu board board1.
In this project the fingerprint module from mixes biometrics is used.
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.
2 principle of operati on the design of security door lock using the finger print technology was.
For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module.
