摘要
随着单片机技术的发展和进步,单片机在日用电子产品中的应用越来越广泛。设计了以AT89C51为核心,采用DS18B20为温度采集模块和液晶显示模块的单片机控制数字体温计。该数字体温计与普通的水银体温计相比,具有测温时间短、范围广、读数准确和方便显示等优点。整个设计系统简单,操作灵活,可编程度非常高。
Technology of single chip microcomputer （SCM） is widely applied in daily electric products. This paper elaborates a digital thermometer designed by AT89C51 SCM. It is controlled by the SCM which uses DS18B20 as its temperature acquisition module and liquid crystal display module. Compared to normal mercury thermometer, it has many advantages. It is characteristic of short time-consuming and wide application in temperature measuring, accurate reading,convenient display and so on. The system is uncomplicated, flexible in operation and highly programmable.
