ABSTRACT
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.
This project uses regulated 5v, 750ma power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/18v step down transformer.
