摘 要 随着时代的进步和发展，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,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。随着人们生活水平的不断提高,单片机控制无疑是人们追求的目标之一，它所给人带来的方便也是不可否定的，其中数字温度计就是一个典型的例子，但人们对它的要求越来越高，要为现代人工作、科研、生活、提供更好的更方便的设施就需要从数单片机技术入手，一切向着数字化控制，智能化控制方向发展。  ABSTRACT With the progress and development, single-chip technology has spread to our lives, work, research in various fields has become a relatively mature technology, this article will introduce thesingle-chip microcomputer-based control of a digital thermometer, the thermometer are multi-purpose thermometer, you can set upper and lower temperature alarm, when the temperature range is not set, it could be reported. With the continuous improvement of peoples living standard, single-chip control is undoubtedly one of the objectives pursued, it gives people the convenience can not be negative, in which digital thermometer is a typical example, but it is what is required of it more and more people to work, scientific research, life and more convenient to provide better facilities will need to start from the number of single-chip technology, all toward the digital control, intelligent control of direction. Single-chip electronic products in the daily application of more and more widely, the temperature is often the need for daily life in a measurement and control volume. Development of science and technology development and testing are closely related. Modern methods to achieve the accuracy, sensitivity and measurement range, to a large extent determine the level of development of science and technology. The author of this article using AT89C2051 MCU and temperature sensor DS18B20 from both hardware and software, introduced a simple digital thermometer of the design process, and schematic diagram of hardware and procedures were concise description of flow chart. Digital thermometer with a traditional thermometer, compared with a reading of convenience, a wide range of temperature measurement, temperature measurement accu
