多功能温湿度表的研制

Development of multifunction thermometer-hygrometer

介绍了一种以半导体工艺制作的高分子薄膜电容式湿度传感器,以热敏电阻器为温度传感器,以高度集成化的专用芯片为后续电路,配以自行开发软件的智能化多功能温湿度表。该产品性能稳定、功耗低、价格廉,具有数字显示温度、湿度及时间的功能。

A thermometer-hygrometer suitable for home application is introduced.It consists of a humidity transducer based on a capacitive humidity sensor,which is made by semiconductor technology,and a temperature transducer based on a thermistor sensor,and a special high-density integrated chip as the follow-up circuit matched with a special software.This product bears the features of low power dissipation,low cost and has the function of digital display of temperature, humidity as well as time.
