This project includes a smart and affordable door lock enhanced with a fingerprint interface.
Fingerprint based door lock system project report.
In this project the fingerprint module from mixes biometrics is used.
Standard door finger print scanner are explained fully in the third chapter of this project report.
For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module.
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.
This system can prove very useful in housing buildings large offices universities and so on.
Because it offers the flexibility to add more features to the system.
It can be controlled through its serial port.
Reason is that rfid card or keys of lock can be stolen password may be leaked.
Circuit diagram of the fingerprint door unlock system the brain of the circuit is arduino uno mcu board board1.
You can add a fingerprint delete a fingerprint and identify the fingerprint.
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.
2 principle of operati on the design of security door lock using the finger print technology was.
The micro controller at89s52 interacts with the module.
