Study And Design On Low Cost Humidity Calibrate System

Air humidity is closely related to mankind. People's daily life and producing activities as well as the growth and existence are closely linked with the humidity of environment. With the development of science and technology, the technology of humidity measurement has been widely used in many fields, such as store management, production manufacture, meteorological observation, scientific study, daily life and so on.Of all humidity measurement, humidity sensors are often used. But because of the characteristic quantity of humidity induction of humidity sensors does not immediately denote environment humidity, this sensor's characteristic must be tested and screened in the process of manufacture, manufacturer of produce and use sensors also need calibrate these. However the price of humidity generators is not only high but also it's cubage is very big, all of these cause the low efficiency and the high price of the examining work. So humidity calibrate is a big problem that affects the manufacture and use of humidity output.Now a humidity calibrate system which has been researched and...
