Abstract

This system is capable of counting the numbers of person entering a restricted area. This system is also capable of switching on/off various electrical and electronics instruments immediately on entry/ departure of persons as per the predefined software. The system also indicates the remaining number of persons in a hall in the event of anybody not leaving a hall.

Access control technology eliminates the need to replace locks and keys in response to every event that might compromise building security. The facility manager can simply cancel the authorization of the access-control card in question and issue new cards when necessary. Still, access control technology carries a capital expense that may be difficult to build into a budget.

This project and implimentation Access Control System is used in the places where we need more security. It can also used to secure lockers and other protective doors. The system comprises a number keypad and the keypads are connected to the 8 bit microprocessor 8085 through the programmable peripheral IC 8255. This is one of the popular microprocessor.
The microprocessor continuously monitor the keypad and if somebody enters the password it will check the entered password with the password which was stored in the memory and if it they are same then the microprocessor will switch on the device.
In our Project we are controlling a electrical device. The password can be an four digit number. If we enter the correct password then the microprocessor will switch on the load. If we want to switch off the load simply press the digit 0 in the keypad.
