MOBILE JAMMER & AUDITORIUM CONTROL SYSTEM
Abstract:
         The Embedded Technology is now in its prime and the wealth of knowledge available is mind-blowing. Embedded technology plays a major role in integrating the various functions associated with it. This needs to tie up the various sources of the Department in a closed loop system. An embedded system is a special-purpose computer system designed to perform a dedicated function. Unlike a general-purpose computer, such as a personal computer, an embedded system performs one or a few pre-defined tasks, usually with very specific requirements.
       This proposal greatly reduces the manpower, saves time and operates efficiently without human interference. This project puts forth the first step in achieving the desired target. With the advent in technology, the existing systems are developed to have in built intelligence.

INTRODUCTION:
        In our project we are going to design an “MOBILE JAMMER & AUDITORIUM CONTROL SYSTEM”. This project is used for avoid mobile phone usage in a particular area for example class room, conference hall, jail room etc.., This project concept is all mobile phone used for particular frequency. The Up-link frequencies are 890 MHz’s to 950 MHz’s. The down link frequency are 935 MHz’s to 960 MHz’s. The bandwidth is 25 MHz’s. So, all mobile phone used this range of frequency (890 MHz’s to 915 MHz’s).




   The internal oscillator is connected to PIC-16F877A controller.This internal oscillator frequency range is set mobile phone bandwidth range. So, mobile phone signal will collapse and automatically mobile phone signal disconnected. Power set for 10 Feet, automatically controlled one room. Increased power Feet and automatically increased distance. The PIC-16F877A controller connects to driver circuit and driver circuit connects to Relay. This relay used for automatically ON & OFF for fan. Embedded programmed by more than four people go to room automatically ON Relay. So, fan is rotated. The entering people counted for IR sensor. So, IR transmitter and receiver sensor used for our project.
