In this era of rapid development of information, as one of the most classic single chip micro-controller, microcontroller technology has spread to our lives, work, research in various fields, has become a relatively mature technology. Since the advent of single chip, continuously improve and perfect their performance, their resources while meeting the needs of many applications, combined with high integration single chip, function, speed, small size, low power consumption, easy to use, low price and so Therefore, in industrial control, smart instrumentation, data acquisition and processing, communication systems, advanced calculators, home appliances and other fields is used widely, and is gradually replacing the existing multi-chip microcomputer application system. SCM potential has been growing attention. As an electronic professional students, we study the SCM, you should put it to skillfully applied to lives. This article describes a microcontroller-based digital thermometer, the thermometer is multi-function thermometer, you can set the upper and lower alarm temperature range when the temperature is not set, can the police. This digital thermometer designed with easy reading, a wide range of temperature measurement, temperature measurement accuracy, digital display, and wide application and so on.
In this information age, the high-speed development of the microcontroller as one of the most classic micro controller, microcontroller technology has spread to our life, work, research, each domain, has become a more mature technology. SCM, its performance since since the advent continuously improved and perfected, its resources and to meet the needs of many applications, together with single-chip microcomputer and powerful function with high integrity, high speed, small volume, low power consumption, easy to use, inexpensive, therefore, etc in industrial control, intelligent instrumentation, data acquisition and processing and communication system, advanced calculator, household appliances, etc are applied widely, and is gradually replace the existing more pieces of microcomputer application system. SCM is increasingly concerned by potential. As electronic professional students, we studied the microcontroller, you should do it skilled application to life. This paper will introduce a kind of digital thermometer based on single-chip microcomputer control, the thermometer belongs to the multifunctional thermometer, can install fluctuation alarm, when the temperature is not setting temperature range, can report to the police. This paper designed digital thermometer readings is convenient, with wide range of temperature, temperature measurement precision, the digital display characteristics, wide application scope.
