The main objective of this project is to develop an embedded system, which is
used to verify and authenticate the authorized
This project is implemented 8051 based At89s52/AVR-Atmega16 developed
board interfaced with I-Button, Keypad, buzzer and LCD,GSM.
The i-Button is a computer chip enclosed in a 16mm thick stainless steel can.
Because of this unique and durable container, up-to-date information can travel with a
person or object anywhere they go. The steel i-Button can be mounted virtually anywhere
because it is rugged enough to withstand harsh environments, indoors or outdoors. It is
small and portable enough to attach to a key fob, ring, watch, or other personal items, and
be used daily for applications such as access control to buildings and computers, asset
management and various data logging tasks.
Whenever the student enters into the college, he has to keep his I-button to the
reader which is attached to our microcontroller based embedded System. At that moment
the reader will checks weather the information of the student is correct or not and then it
will decide whether to give access to that particular person or not. If the information of
the student is correct then he will be permitted inside otherwise he will not permit inside
and switches on the buzzer. The information of the student will be send to the parent
through one wire protocol GSM. And the information of the access system will be
displayed on the LCD which we embedded to our board.
