Wireless Sensor Network Security System (P-0123) (MFN 5491)

Abstract

Intrusion detection is a surveillance dilemma of rational importance that is well suited to wireless sensor networks. In this project, we study the functions of sensor networks to the intrusion detection problem and associated problems of categorizing and tracking object. Our approach is on the base of solid, scattered, wireless network of poor sensors combined into freely rational sensor array. The purpose of combining the hardware and software was to build a machine that is efficient enough to detect the motion through wireless sensor network in the specified filed and move the gun towards the sensing unit automatically. The gun can also be controlled with the help of wireless dedicated camera by a person sitting in base unit receiving live streaming of field. Wireless communication is being used as the range of the wireless can be increased according to one’s need also it is fast and reliable. This mechanism can be placed in any terrain and can work efficiently. PIR sensors are used to detect human detection. If any person is in the range of these sensors the signal is send to microcontroller, which send this signal through NRF module wirelessly to another microcontroller which is placed with automatic gun. Then data is processed by this microcontroller and gun automatically moves towards the targeted sensor and start fairing. In the manual mode the gun can be manually control by command and control center and the command sent by control center is communicated through xbee module to move the gun or start firing.
