Abstract:To solve the problems of complex wiring and high cost for college campus fire detection, this paper proposes a scheme for fire monitoring system based on wireless sensor network. The system collects data with corresponding sensors for various physical elements of the fire,and uses ZigBee technology to form a wireless sensor network, for which the hardware and software for each node are selected and designed, and the upper computer monitoring interface is designed with Labview software. This system can effectively monitor the campus fire information and sound the alarm.
