Study of the Preparation Technology and Mechanics of the Compound Temperature-Humidity Sensor

摘要

The development and character of compound temperature-humidity sensor were discussed in this study. The design of sampling, control and output unit of temperature-humidity sensor as well as their manufacture method and character were studied in detail. The relationship between components of humidity resistance materials and negative temperature coefficient (NTC) thermistor materials in sampling unit of compound sensor and character of electrical resistance and temperature was obtained. Couples of character curves of compound temperature-humidity sensor and data of materials of sampling unit were shown in this paper too.
