(Developed a set of safe temperature online monitoring system based on ZigBee technology. Taking the MC13213 RF SoC as the hardware approach, the ZigBee2007 protocol stack is used to build Star and Mesh networks respectively, and the functions of temperature monitoring and spatial positioning are realized on the host computer monitoring software. The test shows that: the system has an accuracy of 0.175°C and 1.1045m, complete functions, office work, and good expansibility.)
