摘要 溫度計(jì)不僅在工農(nóng)業(yè)科學(xué)研究領(lǐng)域非常普遍，而且在日常生活中也非常的普及。隨著時(shí)代的發(fā)展，溫度計(jì)的發(fā)展也十分的迅速，從過(guò)去主要使用熱偶電阻為溫度傳感器到現(xiàn)在發(fā)展到基于單片機(jī)的數(shù)字溫度計(jì)。相比較傳統(tǒng)溫度計(jì)，數(shù)字溫度計(jì)具有準(zhǔn)確度高、不易誤讀、分辨率高、使用簡(jiǎn)單、電路設(shè)計(jì)簡(jiǎn)單、成本低等特點(diǎn)。本文主要詳細(xì)描述基于AT89S51單片機(jī)系統(tǒng)，利用數(shù)字溫度傳感器DS18B20的數(shù)字溫度計(jì)。

The design of the digital thermometer
Abstract Thermometer is very common in the field of industrial and agricultural scientific research not only measuring instrument, and also is very popular in our daily life. Along with the development of the era, the development of the thermometer is also very rapidly, main resistance when using thermocouple temperature sensor from the past to the present development of the digital thermometer based on single chip microcomputer. Compared with the traditional thermometer, digital thermometer has high accuracy and is not easy to misread, high resolution, simple to use, simple circuit design, low cost, etc. This paper described in detail based on AT89S51 system, using digital temperature sensor DS18B20 digital thermometer.
