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 developed board interfaced with I-Button, Keypad, buzzer and LCD. 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 authorized person enters into the home, he has to keep his Ibutton to the reader which is attached to our microcontroller based embedded board. And enters the password through the keypad interfaced. At that moment the reader will checks weather the information of the person is correct or not and then it will decide whether to give access to that particular person or not. If the information of the person is correct then he will be permitted inside otherwise he will not permit inside and switched on the buzzer. If the person given information is correct then allow to switch on the appliance through keypad. And the information of the access system will be displayed on the LCD which we embedded to our board. .net projects in mangalore,8051 projects,academic projects in mangalore,arm based projects,avr microcontroller projects,b.tech projects in mangalore,diploma based final year projects,dsp/dip projects in mangalore,electronics final year projects,embedded projects in mangalore,final year projects mangalore,industrial based projects,live projects in mangalore,m.c.a projects in mangalore,m.s projects in mangalore,m.tech projects in mangalore,mini projects in mangalore,robotics based projects,simulation projects in mangalore,vlsi projects in mangalore http://www.ieeedeveloperslabs.in/
