湿度同温度一样,与我们的日常生活密切相关。但是由于其分布不均匀,对温度等因素的依存性非常大,使湿度的计测和控制长期以来发展缓慢。随着科学技术的发展,自动控制、微电脑的应用日新月异,人们对湿度的认识也有了新的变化,工业生产中高精度的湿度控制,农业生产上的温室育苗、仓库、办公室、家用电器的空调装置都要求 Humidity, like temperature, is closely related to our daily life. However, due to its uneven distribution, the dependence on temperature and other factors is very large, so that the measurement and control of humidity have been slow to develop for a long time. With the development of science and technology, automatic control, the ever-changing application of microcomputer, people’s understanding of humidity has also been a new change in industrial production of high-precision humidity control, agricultural production of greenhouse nurseries, warehouses, offices, household appliances, air conditioners All required
