Door Control Using RFID project is developed for the users to control a door through RF ID. The main modules in this project are RF Tag, Card Reader, Microcontroller unit and PC.
The card is a specially designed card. Each employee in the company will have the Card.
The card reader is connected with the main door. As soon as a employee scratches a card near the sensor, it evaluates the card 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. It also puts attendance for the particular day with correct time.
The design and port programs are written in Visual Basic. The microcontroller programming is written in assembly language
