HOME SECURITY USING WIRELESS SENSOR NETWORK UNDER THE ESTEEMED GUIDANCE OF: P.RAMESH D.SIVOM( ) KANMANI RAVI( ) B.SAI RAJSEKHAR( ) PUNIT KUMAR( ) C.SUJITH REDDY( )

OBJECTIVE To construct an efficient security system that can monitor various parameters online, using the concepts of wireless sensor nodes and internet protocols. The basic aim of the project is to concentrate on the reliable data transfer during the wireless transmission, which is the basic drawback present in it.

The objective of this project is to provide home security using two methods : 1.Detection of intruder using PIR sensor 2.Intruder image is taken by camera and this information is wirelessly transmitted using zigbee protocol over the ethernet.

WHY ZIGBEE/XBEE? Reliable Mesh networking Low data-rate applications Very long battery life Secure Scalable Low cost Global applicability The reason for promoting a new protocol as a standard is to afford interoperability between devices manufactured by different companies. Xbee is a brand of radio that supports a variety of communication protocols, including Zig-Bee, , and WiFi, among others. XBEE

Frequency: 2.4 GHz Power output: mW Range: 40 m km Data rate: 250 Kbps XBEE PRO Series 2 (XBee) Supply voltage: 2.1 – 3.6 VDC Transmit current 3.3 V): 35 mA (40 mA boost mode) Receive current 3.3 V): 38 mA (40 mA boost mode) Power-down current: <1 uA 25 °C) Indoor/Urban range : 133 ft (40 m) Outdoor/RF Line-of-Sight Range : 400 ft (120 m) SPECIFICATION

 There are 20 pins that can be configured either as digital inputs for sensing switches and other things that operate like switches, or as digital outputs for controlling LEDs and small motors directly. There are some pins that even act as Analog inputs and analog Outputs.  To configure the XBee radio for direct input, output, or both, you’ll use a set of AT commands that select each pin’s mode and the sample rate for sending the data.
