文档介绍：摘要
在这个信息化高速发展的时代,单片机作为一种最经典的微控制器,单片机技术已经普及到我们生活,工作,科研,各个领域,已经成为一种比较成熟的技术,作为电气工程及其自动化专业的学生,我们学习了单片机,就应该把它熟练应用到生活之中来。
温度计,是测温仪器的总称,可以准确的判断和测量温度。温度计现在广泛应用于医疗、科研、制造、生活等各个方面,要求也越来越高。一般的老式的温度计是利用液体、气体受温度的影响而热胀冷缩等的现象为设计的依据。但是这种温度计的精度和准确性却不一定很好。
而随着科学技术的发展,现在又推出了一些新式的电阻温度计、温差电偶温度计、辐射温度计和光测温度计、双金属温度计等,它们则是依据热敏电阻、电磁辐射等的影响设计的,应用领域更广,性能更好。而温度计的发展趋势就是精度越来越准确,使用越来越方便,范围越来越广等。所以我们应该把一些现行的比较先进的技术应用于温度计的设计和制造。
本文将介绍一种基于单片机控制的数字温度计,本温度计属于多功能温度计,可以设置上下报警温度,当温度不在设置范围内时,可以报警。本文设计的数字温度计具有读数方便,测温范围广,测温精确,数字显示,适用范围宽等特点。但是此温度计也有着测温范围有限制,测温精度会因为温度传感器的不同而有所影响,不过用于一般的生活、工作等是可以胜任的。

Abstract
In this information age, the high-speed development of the microcontroller as one of the most classic micro controller, microcontroller technology has spread to our life, work, research, each domain, has e a more mature technology, as electrical engineering and automation specialized student, we studied the microcontroller, you should do it skilled application to life.
The thermometer, is the floorboard of temperature measurement instrument, can accurate judgment and measure temperatures. The thermometer now widely used in medical treatment, scientific research, manufacturing, life, and other aspects, demand more and more is also high. General old-fashioned thermometer is by using liquid, gas and heat bilges cold shrink the influence of the temperature of the phenomenon such as the basis for design. But this thermometer precision and accuracy is not necessarily good.
But with the development of science and technology, now again launched some new resistance thermometers, temperature electric dipoles thermometer, thermometer and light measurement thermometer, two-metal thermometer, etc., which is based on thermistors and ic radiation effect of design, application field better performance and more. And the development trend of the thermometer is more accurate, use precision more and more convenient, more widely, etc. So we should put some current of the more advanced technolo
