基于DS18B20测温的ARM温度采集系统研究

Temperature acquisition system of ARM based on DS18B20

通过研究实现了以ARM为核心的温度采集系统,采用数字温度计芯片DS18B20构成测温单元,设计了DSl8B20与ARM连线图,并介绍了如何实现温度采集以及与PC机间的数据通讯。PC机可把接收到的ARM采集到的温度数据进行整理并显示,具有一定的实用价值。

In this article,it introduces the temperature acquisition system that core of the ARM,to constitute a unit by using digital thermometer chip temperature DS18B20,to design DSl8B20 and ARM wiring diagram,and describes how to achieve temperature acquisition as well as the data communications between PCS.PC can collate the collected temperature data of ARM and display,this design has a certain practical value.
