ABSTRACT

The humidity examination which is widely used inindustry, agriculture, national defense and so on .the humidity examinationwhich is widely used because that the system which uses microcontrollertechnology is volume small and reliability. This article has carried on theanalysis design to the humidity examination system. First, the application and developmentcondition of the humidity examination technology is made a simple introduction.And then, the humidity examination of commonly used method which has enumeratedthe characteristic as well as each one .The point of the article is the designof the hardware and software. In the process of hardware designing, the functionand the characteristic of each part of electric circuits which has made asimple introduction in detail. Meanwhile, the humidity sensor HM1500 and thechip of the A/D transformation to the system in TLC1549 have been made thesimple introduction. In the process of software designing, I have drawn up eachprogram module flow chart, and introduced each module function in detail. Thento the procedure repeatedly revision, it has been consummated the softwaresystem. Finally, I has completed the over all system designing. This system havethe characteristic of sensitivity high and the reflection time is short, and soon .It has the intellectualization, and programmable and small, then takesalong short, and so on. It believed that this system has the widespreadapplication .

Keywords： mcu, humidity examination，software system, hardware system
