| Abstract: | Distributed temperature sensing system is proposed and its principle is explained based on DS18B20. The experimental cortfiguration and the circuital structure are that information of the temperature are acquired from the node. The operation and principle of the essential device DS18B20 are that a gleam of the manner is adopted in the serial communication and the methods for integral data process and decimal data process are described. The soft structure of the system is analyzed. Finally the experimental results are obtained , which shows that the proposed system is very practical. |
