SYNOPSIS
Now a days, a problem of security is very much important everywhere in the world. So, in large firms or companies, to make protect of entering of unauthorized person or to secure their important section, they generally use this type of security.
It is quite easy in installation and use. Through this, one can allocate more number of passwords to many fellows. It is easy to use as the fellow don’t need to carry any type of id card or chip etc.
This project, AN ACCESS CONTROL SYSTEM provides a facility of security. This type of security lock is generally attached at the main entrance door of the firms. By using this type of security, only authorized fellow can enter.
It is quite easy in installation and use. Through this, one can allocate more number of passwords to many fellows. It is easy to use as the fellow don’t need to carry any type of id card or chip etc.
CIRCUIT DIAGRAM
DESRIPTION
BLOCK DIAGRAM & DESCRIPTION
First of all a user enters a password by a hex keypad.
Micro controller checks password and then gives according output.
If the password is correct then it opens the door.
If the password is wrong then it gives output to the alarm.
DESRIPTION When the power supply is switched on, then the whole circuit starts working.
Then in LCD, the name of company is displayed and the person is asked to enter the password.
The password is entered through a hex keypad.
The microcontroller compares that password with the already saved database of employee's information.
If it matches with any of the saved password, then microcontroller gives output to the LCD.
Then in LCD, the name of employee, his department, his employee number, etc are displayed.
Parallel, the microcontroller gives output to the DC motor to open the door.
If the password doesn’t match with any password three times, then microcontroller displays in LCD that your password is wrong, and it gives output to the buzzer.
