基于单片机的温湿度检测系统01.doc

摘要 随着人们的生活及其生产水平的不断提高，对生活环境和生产环境的要求就显的尤为重要,温湿度的控制就是一个典型的例子，因此温湿度检测系统就是现代生产生活中应运而生的一种智能、快捷、方便可靠的检测系统，特别是在工业生产中如果检测得不准确就会发生许多的生产事故。如化工生产中对温度的检测不当就会导致生产效率的降低和产品质量的下降。而现在所使用的通常都是精度为10.1℃的水银、煤油或酒精温度计。这些温度的刻度间隔通常都很密，不容易准确分辨，读数困难，而且他们的热容量还比较大，达到热平衡所需的时间较长，因此很难读准，并且使用非常不方便。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 As peoples lives and the continuous improvement of production level of the living environment and production environment is particularly important on the obvious, temperature and humidity control is a typical example, it is temperature and humidity detection system came into being the life of modern production A smart, efficient, convenient and reliable detection systems, especially in the industrial production is not accurate if the detection of the production occurs in many accidents. Chemical production, such as the detection of temperature can lead to inappropriate production efficiency and product quality to reduce the decline. And now used in temperature and humidity detection system is usually an accuracy of 1 ℃ or 0.1 ℃ mercury, kerosene or alcohol thermometer the temperature detection and physical simulation using traditional methods of quantitative detection of humidity. These temperature and humidity testing of calibration intervals are usually very dense, it is not easy to distinguish accurately, reading difficulties, and their relatively large heat capacity to heat balance the time required is longer, it is difficult to read accurate, and very inconvenient to use.  Work for the modern, scientific research, to provide a better life more convenient for the facilities will need to start from the single-chip technology, all toward the digital control, intelligent control of direction. The design is based on single-chip microcomputer as the core, with the temperature sensor (DS18B20) and humidity sensor (HIH-3610), and related peripheral circuits of the detection system components, you can receive the measured temperature and hum
