摘　　要： 本文介绍了一种高分子湿敏元件与LM555定时器组成的湿/频式湿度探测器的工作原理、探测电路的参数优化问题以及标定数据的处理方法,对湿度标定的标准进行了简单的概述;针对本装置应用特点,就饱和盐溶液相对湿度标定的方法、盐种类和测试辅助仪器的选择以及标定中应该注意事项进行了具体地叙述。此外,文章还分析了读取试验数据常用的两种方法：仿真器直接读取和能过串行接口读取。 The principle of the humidity detector consisting of macromolecule humidity and ML555 timer is introduced, how to optimize the performances of the humidity detector and process the collected data are also presented. The standard of humidity calibration is described simply. Based on the humidity detector itself and the environment it runs in, how to choose the type of the salts and other subsidiary implements are discussed. Two kinds of methods for collecting the test data produced in response to different humidity by emulator and by serial interface are analyzed , and a comparison between these two methods are made.

关 键 词： 高分子湿度探测器 参数优化 饱和盐溶液 串行接口
