AT89C52 microcontroller as the control center to use SHT10 digital temperature and humidity sensors sensor, SHT10 digital temperature and humidity sensor detects the granary of the current humidity and displays humidity values, and can take the initiative to set up the alert humidity range. When the barn so as to achieve realtime alert humidity range when the green light, no alarm。 And when real barn humidity exceeds the warning area, the red light and buzzer alarm. Thus pleting the design requirements for the granary humidity detection and alarm function. This design is the automatic detection and alarm systems, conventional manual testing are very different. Compared to the previous manual inspection have greater advantages, can be solved manually detect the presence of timeconsuming, inefficient, humidity detection error, detection of randomness and other shortings. The design is not only low cost, easy to use and accurate measurement. Due to the above advantages, the design is very conducive to largescale promotion in our country, can improve the ability of China39。s grain storage, grain storage on China made great contributions, but also conducive to the country39。s longterm stability to provide material security.Key words: Humidity。 buzzer。 LCD。 SCM鹽城工學(xué)院本科生畢業(yè)設(shè)計(jì)說(shuō)明書（2022）目 錄1 概 述 ...........................................................................................................................1 課題研究背景及意義 .................................................................................................1 課題設(shè)計(jì)內(nèi)容 .............................................................................................................1 課題設(shè)計(jì)目標(biāo) .............................................................................................................2 課題預(yù)測(cè)效果 .............................................................................................................22 系統(tǒng)總體方案設(shè)計(jì) ...........................................................................................................3 濕度檢測(cè)報(bào)警系統(tǒng)原理 .............................................................................................3 總體思路 .....................................................................................................................3 具體模塊 .....................................................................................................................33 系統(tǒng)的硬件設(shè)計(jì)與實(shí)現(xiàn) ...................................................................................................5 主控制模塊 .................................................................................................................5 檢測(cè)模塊 .....................................................................................................................9 顯示模塊 ...................................................................................................................12 報(bào)警模塊 ...................................................................................................................14 設(shè)置模塊 ...................................................................................................................15 復(fù)位模塊 ...................................................................................................................164 系統(tǒng)的軟件設(shè)計(jì) .............................................................................................................17 中斷子程序 ...............................................................................................................17 主函數(shù)程序 ...............................................................................................................17 顯示子程序 ...............................................................................................................20 按鍵子程序 ...............................................................................................................215 系統(tǒng)調(diào)試 .........................................................................................................................23 軟件調(diào)試 ...................................................................................................................23 硬件調(diào)試 ...................................................................................................................25參 考 文 獻(xiàn) .......................................................................................................................28致 謝 .............................................................................................................................29附 錄 .............................................................................................................................30附錄 1：程序清單 ......................................................................................
