Security monitoring systems are popular in home automation, and Zigbee is a new industrial standard wireless sensor networks. This paper introduces an experimental home security monitoring and alarming system based on Zigbee technology, it is capable of monitoring door & window magnetic contact, smoke, gas leak, water flooding, providing simple controls such as turning off the valves, and sending the alarms to the residential area security network etc. The security alarming system is based on Zigbee chip MC13192 and low power consumption micro-controller MSP430F135. A description of the system architecture, circuit principle and the firmware flowchart is presented. The system uses a control key fob for activating and de-activating the alarm easily, supports Web interface so that user can access the system remotely to control, search or review the history record, and offers a LCD panel for simple configuration. The experimental system has been designed and its wireless communication test result shows that the Zigbee wireless network can improve the home security with low power and easy to implement solution.
