I题目：花园自动浇灌系统的设计摘要随着时代的进步，人们的生活形态更加自动化、智能化，如何将科技融入生活，如何节省人力提高效率成为现如今热门研究课题。植物是现代人类生活不可或缺的一部分，如何高效又节省人力的照料好这些植被，科技是最重要的一部分，科技参与到植物养殖的过程中，便有了花园自动灌溉的理念。本文的设计是实时监测土壤的温度和干湿度处于一个适合植物生长的环境。这款电路的最重要的部分是由STC89C52单片机和传感器还有ADC0832共同组成的。土壤的干湿度感应传感器会对土壤的干湿度数据进行收集并发送到ADC0832的IN端口。此电路利用了信息采集分析进行AD转换，MCU解码器等功能的实现。花园灌溉系统能够分成两类其中一类是智能另一类是手动进行浇灌：这两类当中需要使用单片机的类型为智能浇灌系统来确定水的范围，而后把感应电路的土壤水分值传递给单片机。当数值低于下限的时候，MCU发送出信号来控制是否进行浇灌，假如上线设置的值比较高的状态那么就利用单片机来进行进行数据传送如果想要达成停止浇灌的目的，就需要利用同样的信号来进行传送;需要手动来操作的部分就需要使用单片机和外围电路进行供电。关键词：花园自动灌溉STC89C52土壤干湿度温湿度传感器IIIIIAbstractWiththeprogressofthetimes,people’slifeformsaremoreautomatedandintelligent.Howtointegratetechnologyintolifeandhowtosavemanpowerandimproveefficiencyhavebecomehotresearchtopics.PlantsareanintegralpartofmodernhumanlifeHowtoefficientlyandlabor-savinglycareforthesevegetationisthemostimportantpartofscienceandtechnology.Intheprocessofbreeding,thereistheconceptofautomaticirrigationofgardens.Thedesignofthispaperisacircuitmodelthatplansandproducesmoisturetoputthesoilinaneutralstate.ThemostimportantstructuralsetupforthiscircuitisthecombinationoftheSTC89C52randtheADC0832.Thedry-humiditysensorofthesoilcollectsdry-humiddatafromthesoilandsendsittotheINportoftheADC0832.ThiscircuitmakesuseoftheinformationacquisitionandanalysisofthesoildrynessandhumiditytoperformfunctionssuchasADswitchingandMCUdecoding.Automaticirrigationcanbeeitherintelligentormanual:Thedry-humiditysensorofthesoilcollectsdry-humiddatafromthesoilandsendsittotheINportoftheADC0832.ThiscircuitmakesuseoftheinformationacquisitionandanalysisofthesoildrynessandhumiditytoperformfunctionssuchasADswitchingandMCUdecoding.Thesmartpartistheuseofartodeterminetherangeofwater,andthentransferthesoilmoistureofthesensingcircuittothe.Whenthevalueislowerthanthelowerlimit,theMCUsendsasignaltocontrolthewater.Whentheupperlimitishigherthantheupperlimit,theisoutput.Theuseofsignaltransmissiontocontrolthesystemtostopwatering;theandperipheralcircuitsofferthepower.KeyWords:AutomaticgardenirrigationSTC89C52drysoilmoistureIV目录摘要..................................................................IAbstract..............................................................II引言...................................................................11绪论..................................................................21.1花园自动灌溉系统研究的意义及背景....................................21.2系统整体结构设计....................................................31.2.1核心模块...........................................................31.2.2显示模块..........................................................31.2.3转换模块..........................................................32系统硬件电路设计......................................................52.1单片机最小系统设计..................................................52.1.1STC89C52的简介...............................
