摘要 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器，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。本文通过采用的温度报警器的设计，阐明了该装置进行设计与制作的具体过程及方法。这种温度报警器结构简单，可操作性强，应用广泛。工作时，温度测量范围为oＣ。从而防止带来的不必要的损失。STC89C51单片机，数字控制，温度计DS18B20，AT24C02 ABSTRACT Single chip technology has spread to we live, work, scientific research, each domain, has become a mature technology, this paper introduces a kind of based on single chip microcomputer control digital temperature device, the thermometer belongs to the multi-function thermometer, can set up and down the temperature alarm, when the temperature is not set range, you can call the police. With modern industrial and agricultural technology and the development of people to the improvement of the living environment requirements, and people urgently need to test and control the temperature. Through the use of components of the buzzer as acoustic temperature alarm design, it is expounded that the device for the design and production of the specific processes and methods. The temperature alarm simple structure, the maneuverability is strong, wide application. Work, temperature measurement range for 5-38 ? C. The current environment temperature if more than the high temperature of setting the critical temperature, issued a warning signal by single-chip microcomputer, thus preventing bring unnecessary losses. High temperature caused by fire are: electric short circuit, overload, contact resistance by too high temperature or fire; Electrostatic generation high temperature or or fire; Lightning and lead to high temperatures or high voltage into the fire; The main room is in air conditioning equipment such as computer, electricity work long hours, cause of old equipment, air conditioning fault, and cant cooling; So the telecom room belongs to electronic products fever fast, in a short time, computer room temperature beyond normal temperature equipment, cause the system to produce paralysis or fire, when temperature alarm
