But in a conventional environment parameters, humidity is the most difficult to accurately measure a parameter. This is because is much more complex than the measurement temperature measuring humidity, temperature is an independent is measured, and the humidity is affected by other factors (atmospheric pressure, temperature). In addition, the standard of humidity is also a problem. Foreign production of humidity calibration equipment is very expensive. In recent years, both at home and abroad has made great progress in the field of research and development of humidity sensor. Moisture sensor is from simple moisture sensor to integration, intelligent, the direction of the rapid development of multi-parameter detection, for the development of a new generation of humidity/temperature measurement and control system has created favorable conditions, and to increase the humidity measurement technology to a new level.
