SMART CARD BASED DOOR LOCK SYSTEM

1. Scope of work Understanding of IR sensor and its importance.

Microcontroller programming in C language.

Understanding of ‘Embedded system’

PCB designing and Circuit designing of circuit.

PCB development, Component mounting and soldering.

Testing of the circuit

2. IntroductionSmart card systems are widely used by many different organizations to provide both

convenience and security. Hotels use them for room access; credit card companies

use them for handling purchases, and college campuses use cards for both building

access and electronic payments.

A smart card is a type of plastic card embedded with a computer chip that stores and

transacts data between users. This data is associated with either value or information or

both and is stored and processed within the card’s chip, either a memory or

microprocessor. The card data is transacted via a reader that is part of a computing

system.

Through this project we presented the prototype of ‘Smart card’ which is also used to

control the door lock system.

3. MotivationSmart card system is one of the safest mode to lock the home as to unlock the door that

particular swap card is required. Until and unless that swap card is not used to unlock

the door, no one can succeed in order to enter the home by the means of door in which

this system is installed. The main reason behind designing this project is to decrease

number of robbery and burglary in the city and especially in metropolitans. As today’s

generation is working, security is very important for their home. Hence, to provide

better security system we have designed the following system.

4. Objective(s)The fundamental requirements for the smart card based door lock system

remained fixed throughout the design process. The goal was to design a system

which would allow the user automated and convenient access to the door system. The

fundamental objectives of the system include:

Programming in proper manner

Interfacing to be done in a right manner

5. Project OverviewIn the project the name of the components which were used in it are as follows:

1) IR sensor

2) Microcontroller

3) Motor driver

4) Dc motor

Here as the person enters the card it passes through the area where IR sensor is placed

.Once it crosses that area the system came to know that some card is entered and drives the

motor to move the card inside passes to a certain limit. After reaching a particular point, it

will be stopped. The; card consists of a particular pattern of holes which will be detected

;either hole is present over there or not if its present then it will ask for the password .Now

you have to enter the password in between if the entered code is wrong and it happens for

three times then it will cancel whole task and makes you unable to collect the card otherwise

the system will unlock if code is correct.

We will be using 8 bit ATMEL microcontroller AT89S8253. It is a low-power, high-

performance CMOS 8-bit microcontroller with 12K bytes of In-System Programmable

(ISP) flash program memory and 2K bytes of EEPROM data memory. It has 32

programmable input output lines. The resulting architecture is more code efficient. Outputs

from port pins of the microcontroller are fed input pins of motor driver.

6. Description of workingInsert the card in the card slot, it will ask for the password. Enter the password and the door

will get unlock. But while operating this system you must keep in mind that the code which

you are entering should be the correct one, in case it is wrong for the three time then you

will loose your card.
