Yijian Liu · Physical Experiment of College · 2011
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.
