现代信息技术的飞速发展和传统工业改造的逐步实现。
能够独立工作的温度检测和显示系统应用于诸多领域。
传统的温度检测以热敏电阻为温度敏感元件。
热敏电阻的成本低，但需后续信号处理电路，而且可靠性相对较差，测温准确度低，检测系统也有一定的误差，所以传统的温度计有反应速度慢、读数麻烦、测量精度不高、误差大等缺点。
本文是以单片机AT89C51为核心，通过DALLAS公司的单总线数字温度传感器DS18B20来实现环境温度的采集和A/D转换，用来测量环境温度，温度分辨率为0.0625℃，并能数码显示。
因此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，适用范围宽其电路简单，软硬件结构模块化，易于实现等特点。
数字式温度计的设计将给人们的生活带来很大的方便，为人们生活水平的提高做出了贡献。
数字温度计在以后将应用于我们生产和生活的各个方面，数字式温度计的众多优点告诉我们：数字温度计将在我们的未来生活中应用于各个领域，它将会是传统温度计的理想的替代产品。
第2章系统设计方案方案一：来采用热敏电阻器件，利用其感温效应，再将随被测温度变化的电压或电流采集过来，进行A/D转换后，利用单片机进行数据的处理，然后在显示电路上，将被测温度显示出。
方案二：利用温度传感器，在单片机电路设计中，大多都是使用传感器，所以这是非常容易想到的，所以可以采用一只温度传感器DS18B20，此传感器，可以很容易直接读取被测温度值，进行转换就可以满足设计要求。
分析上述两种方案可以看出方案一是使用热敏电阻之类的器件利用其感温效应，进行A/D转换后，利用单片机进行数据的处理，在显示电路上被测温度显示出来，这种设计需要用到A/D转换电路，感温电路比较麻烦。
方案二是利用温度传感器直接读取被测温度，读数方便，测温范围广，测温精确，适用范围宽而且电路简单易于实现。
综合方案一和方案二的优缺点，我们选择方案二。
除了以上的选择方案，还可以选择别的方案，如传感器的选择改变。
用KTY84-130、HT69-KTY84-130 、KG3044等，只要稍微改一下电路和程序的话就可以实现功能。

此外，AT89C51在空闲模式下，CPU暂停工作，而RAM定时计数器，串行口，外中断系统可继续工作，掉电模式冻结振荡器而保存RAM的数据，停止芯片其它功能直至外中断激活或硬件复位。
同时该芯片还具有PDIP、TQFP和PLCC等三种封装形式，以适应不同产品的需求。

（2）GND：接地。
（3）P0口：P0口为一个8位漏级开路双向I/O口，每脚可吸收8TTL门电流。
当P1口的管脚第一次写1时，被定义为高阻输入。
P0能够用于外部程序数据存储器，它可以被定义为数据/地址的第八位。
在FIASH编程时，P0 口作为原码输入口，当FIASH进行校验时，P0输出原码，此时P0外部必须被拉高。
（4）P1口：P1口是一个内部提供上拉电阻的8位双向I/O口，P1口缓冲器能接收输出4TTL门电流。
P1口管脚写入1后，被内部上拉为高，可用作输入，P1口被外部下拉为低电平时，将输出电流，这是由于内部上拉的缘故。
