The design of check and control system for temperature based on the wireless communications of ZigBee

There are several problems that high cost of chips, slow transmission distance speed in Radio Measuring and Controlling System in corrals, this paper present the design of check and control system for temperature based on the wireless communications of ZigBee. The host controller of this system is SST89C51 single-chip computer, and the data acquisition device is DS18B20. The system not only can realize the real time way of monitoring and Controlling in Corrals, but also has features such as wide monitoring range, low cost, low loss of power, many network nodes and long transmitting distance. The environment of corrals is controlled in the most suitable area for livestock and poultry growth, which favors the yield increase, raises the Economic Benefit.
