Fingerprint based door lock system project report.
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.
Circuit diagram of the fingerprint door unlock system the brain of the circuit is arduino uno mcu board board1.
This project includes a smart and affordable door lock enhanced with a fingerprint interface.
It can be controlled through its serial port.
For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module.
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.
Because it offers the flexibility to add more features to the system.
This system can prove very useful in housing buildings large offices universities and so on.
Fingerprint based door lock our proposed fingerprint based lock system is a reliable and very secure lock that will not only ensure safer environment but also ease lifestyle.
In this project the fingerprint module from mixes biometrics is used.
You can add a fingerprint delete a fingerprint and identify the fingerprint.
Reason is that rfid card or keys of lock can be stolen password may be leaked.
