Development Of Wireless Home Security Modules

Abstract

Home security system is needed for occupants' convenience and safety. In this paper, we present the design and implementation of low cost and low power consumption. The system is a wireless home network which contains a XBEE wireless module and three kinds of wireless security sensor nodes that are door security nodes, infrared security nodes and vibration sensor nodes. The nodes are easy installing. The system can response rapidly to alarm incidents and has a friendly user interface including a LCD (liquid crystal display) and a reset button. The wireless communication protocol between the gateway and the nodes is also suitable for other home appliances. Furthermore, some methods are taken to ensure the security of system information.
