摘　　要：通过对湿度检测的重大意义进行分析,得出了本湿度检测仪的价值和意义,介绍了仪器的设计思路和应用前景,同时介绍了一种特殊的信号采集方法,从而将电阻的变化直接转化为信号的频率变化,再将此高频信号传入单片机,从而实现对信号的数字处理。文章中还涉及了软件程序设计,主要包括频率信号的频率读取和LED数码管显示的Keil C语言程序。By analyzing the significance of moisture detection,we get its value and meaning.In this paper,we introduce the design idea and application prospect,and a special kind of signal acquisition method,thus the resistance changes directly into the signal frequency variation,again the high frequency signal into a single-chip microcomputer,so as to achieve the digital signal processing.This paper also involves a software program design,including read the frequency of the signal frequency and LED digital pipe display Keil C program.
