我国(日本)很早就处于高温多湿的环境下,过去一直致力于以温度为中心的环境控制.但为了能更好地进行环境控制须同时控制温度和湿度.又由于整个工业界都在进行系统化,所度要求研制包括湿度传感器在内的各种传感器.即如家庭用的电气产品中的冷暖房设备的湿度控制,检测干燥机的水分以及电子炉等的食品烹调器的湿度检测等等,都是属于湿度传感器的应用范围.但在这些用途中,由于要求高精的并能稳定地计测宽范围的湿度,所以 Our country (Japan) was very hot and humid very early and has historically been committed to temperature-centric control of the environment, but it has to control both temperature and humidity for better environmental control and because the entire industry is under way Systematize and demanded the development of various sensors including humidity sensors, such as humidity control of heating and cooling equipment in household electrical appliances, moisture detection in food cookers such as moisture in dryers and electronic furnaces, etc. , All belong to the application range of the humidity sensor.But in these applications, because of high precision and stable measurement of a wide range of humidity, so
