S oil testing and display of temperature and humidity system takes Temperature and humidity sen sor SHT 11 as inductive ponents, it will detect the soil temperature and humidity value and input the value to the AT89C51 microcontroller,then the temperature and humidity value will be output to LCD screen displayed. Automatic watering system design for intelligence and manual two watering part through the microcontroller program setting the upper and lo wer water attained,then paring this upper and lower water attained with the vale that throug hing SHT11 inputting to the microcontroller. When below the limit SCM outputs a signal to o pening the Electromagic valve ,and Start watering .if Above the upper limit value,the SCM will output another signal to Turnning off the Electromagic valve ,and Stop watering. Manual part read the time from the clock chip DS1302 by microputer. Through software program to setting the regular watering39。time and Watering box Water level control system u ses Pure hardware control. Realizing realtime monitoring water tank, Automatic water supply and Level alarming function. Keywords: AT89C51 microcontroller。 SHT 11 temperature and humidity sensor。 LCD。 clock chip DS1302。C51 program。 Digital circuit 河南理工大學(xué) 2021 畢業(yè)設(shè)計(jì)說(shuō)明書(shū) III 目 錄 緒論 ................................................................... 1 選題的目的和意義 .................................................. 1 ................................ 1 ..................................... 2 AT89C51單片機(jī) .......................................................... 4 AT89C51單片機(jī)的基本組成 ........................................... 4 AT89C51主要特性 ................................................... 5 ........................................................... 5 AT89C51單片機(jī)的存儲(chǔ)器 ............................................. 7 程序 存儲(chǔ)器 .................................................. 7 數(shù)據(jù)存儲(chǔ)器 .................................................. 8 振蕩電路和時(shí)鐘 .................................................... 9 AT89C51的中斷系統(tǒng) ................................................ 10 中斷系統(tǒng)結(jié)構(gòu)和中斷控制 ...................................... 10 中斷響應(yīng)過(guò)程 ................................................ 12 定時(shí)器 /計(jì)數(shù)器 .................................................... 12 /計(jì)數(shù)器 0和 1簡(jiǎn)介 ..................................... 12 與定時(shí)器 /計(jì)數(shù)器 0和 1相關(guān)的特殊功能寄存器 ................... 13 溫濕度傳感器 .......................................................... 14 數(shù)字溫濕度傳感器 SHT11 ........................................... 15 SHT11的傳感器輸出 ............................................... 16 濕度值輸出 ................................................. 17 溫度值輸出 ................................................. 17 露點(diǎn)計(jì)算 ................................................... 18 非線性校正及溫度補(bǔ)償 ........................................ 18 SHT11的特 性 ..................................................... 19 SHT11的特點(diǎn) ............................................... 19 SHT的詳細(xì)規(guī)格 .............................................. 19 SHT11的引腳 ..................................................... 20 河南理工大學(xué) 2021 畢業(yè)設(shè)計(jì)說(shuō)明書(shū) IV SHT11的的內(nèi)部命令與接口時(shí)序 ..................................... 21 SHT11的內(nèi)部命令 ........................................... 21 SHT11的命令順序及命令時(shí)序 ................................. 21 SHT11的狀態(tài)寄存器 ......................................... 22 硬件接口 ......................................................... 23 恢復(fù)處理 ......................................................... 23 SHT11的相關(guān)程序 ................................................. 24 DS1302時(shí)鐘芯片 ........................................................ 30 DS1302時(shí)鐘芯片的簡(jiǎn)介 ............................................. 30 引腳 ............................................................. 30 命令字節(jié) ......................................................... 31 DS1302的相關(guān)程序 ................................................. 34 液晶顯示器 LCD ......................................................... 38 液晶顯示器的分類(lèi) ................................................. 38 AMPIRE 12864 ................................................... 38 LCD 12864 引腳功能 ........................................ 39 KS0108控制器指令功能 ....................................... 40 應(yīng)用說(shuō)明 ................................................... 42 LCD相關(guān)程序 ................................................ 42 盆花自動(dòng)澆水系統(tǒng)的設(shè)計(jì) ................................................ 49 土壤溫濕度檢測(cè)與控制 .............................................. 49 硬件電路設(shè)計(jì) ................................................ 49 系統(tǒng)軟件設(shè)計(jì) ................................................ 53 蓄水箱自動(dòng)供水系統(tǒng) ................................................ 65 .............................................. 66 ................................................ 67 系統(tǒng)硬件組成 ................................................ 66 系統(tǒng)電路連接 ................................................ 70 參數(shù)計(jì)算 ................................................... 71 水箱水位
