兰州工业高等专科学校 毕业设计（论文）任务书 摘 要 随着计算机技术在社会各个领域的渗透，单片机已广泛地应用到人们工作和生活方面的各个领域，并成为当今科学技术现代化的重要工具。随着单片机的发展，人们对事物的要求越来越高，单片机的应用软件技术也发生了巨大的变化，从最初的汇编语言，开始演变到C语言开发，不但增加了语言的可读性，结构性，而且对于跨平台的移植也提供了方便，另外一些复杂的系统开始在单片机上采用操作系统，一方面加速了开发人员的开发速度，节约开发成本，另外也为更复杂的实现提供了可能。 本设计中用的是AT89C52单片机以及其它辅助芯片的结合来设计一台智能型温湿度计。该温湿度计主要是通过温湿度传感器的感温/湿组件获取环境中的温湿度值，随后通过单片机的处理再经过MAX7219串行LED显示驱动器的转换最后由数码显示器输出该环境下的温湿度值。 该温湿度计应用于温室内温湿度的监测、计算机CPU的温升情况监视、地下室温湿度值的监视等。该温湿度计结构紧凑，携带方便，精度较高，成本低等优点。 关键词: 单片机 、 感温组件 、 数码显示 、 传感器 、 LED显示 Abstract Permeate at social each realm along with the calculator technique, single slice the machine has already applied to each realm of the work and life of people broadly, and become science technique to modernize nowadays of important tool.Along with single slice the development of the machine, the peoples request to the thing is more and more high, single slice the applied software technique of the machine also took place huge variety, from edit collected materials language at the beginning, start turn into to the C language development, increased language not only of readability, structure, and also provided to the transplantation of the cross-platform convenience, moreover some complicated system beginning on board adopt operate system in the single slice, accelerate development the personnels development speed on the other hand, the economy develop cost, moreover also for the more complicated realization provide possibility. This design is convenient is the AT89C52 single slice the machine and the other assistance chip combine to design one hygrometer.The hygrometer mainly is feeling that spreads the feeling machine through degree of humidity/the wet module obtain degree of humidity value in the environment, passing a single slice later on, the processing of the machine passes by again the conversion end that the MAX7219 stringses go the LED manifestation actuator is outputted that environment by the figures display under of the degree of humidity be worth. The hygrometer ap
