基于单片机的数字温度计的设计

 摘要：随着社会的不断发展，人们对新科技的需求量也日益增加。在讲求新元素的同时，还讲求方便、快捷、精准。温度计，人们需要对各种加热炉、热处理炉、反应炉和锅炉中温度进行监测和控制。采用单片机来对他们控制不仅具有控制方便、应用范围广和测温准确，其输出采用数字显示，方便读取。而且可以大幅度提高被控温度的技术指标，从而能够大大的提高产品的数量和质量。该种温度计的控制器采用AT89C51单片机为主控器件，DS18B20为测温传感器通过4位共阳极LED数码管串口传送数据，实现温度显示。

    Abstract:With the continuous development of society, the people of the new technology of demand also increases increasingly. In seeking new elements at the same time, also be convenient, fast, accurate. Thermometer, the people need to all kinds of heating furnace, heat treatment furnace, in the reactor and the boiler the temperature monitoring and control.MCU to use them to control not only has the convenient control, wide application range and accurate temperature measurement, the output of the digital display, easy to read. It can greatly increase the temperature was charged with the technical indicators, which can greatly improve the quantity and quality of products. The thermometer controller using AT89C51MCU as the main controller,S18B20temperature sensor through a total of 4digital tube anode LED serial transmission of data, temperature display.
