The Building of Debris Flow Monitoring and Warning System based on Zigbee Protocol using Multi-sensor Technology

We built a monitor and warn system based on Multi - sensor network, which could monitor data in real time. In order to imitate scene of the monitor areas, we have built a sand table model according to topographic feature, it changed the traditional monitor methods. In this system, we not only designed the hardware, but also investigated the relationship between the sensor nodes distribution and areal geology. The designing methods and ideal of this system also could apply to environmental monitoring and forest fire prevention system.
