在科学技术日益发达的今天,湿度的监测与控制在国民经济各个部门,在国防、科研及人民生活等许多领域有着非常广泛的应用。众所周知,湿度的测量具有一定的复杂性,而对湿度进行控制则更不易实现。这样,人们熟知的毛发湿度计、干湿球湿度计等已不能满足现代要求的实际需要,为此,人们研制了各种湿度传感器。其中物性型湿度传感器以其测量湿度范围宽,或响应速度快,或测量精度高,或稳定性好,体积小,重
With the development of science and technology, the monitoring and control of humidity in various sectors of the national economy have a very wide range of applications in many fields such as national defense, scientific research and people’s livelihood. As we all know, humidity measurement has some complexity, while the humidity control is more difficult to achieve. In this way, well-known hair hygrometer, wet and dry bulb hygrometer can not meet the actual needs of the modern requirements, for which people have developed a variety of humidity sensors. One physical humidity sensor to measure its wide range of humidity, or fast response, or high accuracy, or good stability, small size, weight
