Door Control Using Finger Print Scanner project is developed for the users to control a door through Finger print scanner. It consists of a finger print scanner, PC, microcontroller unit and door controlling system.
The scanner is connected with the main door. As soon as a employee places his finger on the scanner, it evaluates the finger print and sends signal to the computer through serial port. The computer searches the employee from the list and displays the full details of the employee.
If he is an authorized person, it sends signal to the circuit and the circuit generates analogue voltage to the door. Thus the door opens automatically. It he is not an authorized person, the door does not open and it generates a siren and the computer displays the message..
This is very much used in companies where security and authentication are required.
In future, it can be implemented to put attendance for the particular day with correct time.
The design and port programs are written in Visual Basic. The microcontroller program is written in assembly language
