1.ABSTRACT: The soldiers may sometimes cross their area limit without their knowledge. This causes a lot of problems. They may be caught by the other peoples. This project is developed for the soldiers to find out the border. The main modules in this project are RF transducer, ARM controller unit and LCD display. The XBee transmitter is connected at the border area. The XBee receiver with the ARM controller unit will be the under control of commander. When the soldier reaches the particular area, the RF signals are received by the receiver and given to the ARM controller unit. The ARM controller analyses the signal and sends corresponding message to the LCD display and the same information is transmitted to commander via XBee. The receiver which is there at the commander receives the signal which was transmitted from the transmitter via XBee.

4.METHODOLOGY: This project is developed for the soldiers to find out the border and to check whether the person is authorized or unauthorized. The main modules in this project are RF transducer, ARM controller unit and XBee. The transmitter will be there in border area and the receiver will be there at the commander. The transmitter module has two inputs. One is PIR sensor, which is used to detect the persons. And the second is RF receiver, which is used to detect whether the person is authorized or unauthorized with the help of RF transmitter.

If PIR senses a person and RF receiver receives a signal from the RF transmitter, then the ARM controller analyses the signal and indicates the person is authorized via LCD display. And the same information is transmitted to commander via XBee and that will displayed on receiver LCD display. If PIR only receives a signal and sends that to the ARM controller. Then the controller will indicate the person is unauthorized with the help of buzzer and displays on the LCD display. The commander will take appropriate action based on the information received at the receiver end.

5. ADVANTAGES AND DISADVANTAGES: Protecting borders and other strategic areas are key to preventing these illegal activities and maintaining tight national security. Secure and reliable communication. Leading edge technology that meets today's and tomorrow's needs. Preventing unauthorized activity with many national borders stretching for hundreds of kilometers across dramatically variable terrain and climates is an on-going task. A solid border operation can be an effective deterrent to illegal activity, but successful border management requires a combination of efficient systems and effective manpower deployment, supported by strong communications.

DISADVANTAGES: One time investment cost. It has to be planted throughout the border area

6. APPLICATIONS: This project can be implemented to provide a security for Home, Schools, Colleges, Companies. Restricted zones. Wherever security is important there we can implement this project.

7. CONCLUSION: As this project is based on micro-controller(ARM7LPC2148) and XBee technology is used to transmit data this can be of great use in the border and helps the commander to keep a keen eye on the border with the help of PIR sensor, RF Transmitter and RF Receiver in the border area.
