基于单片机的模拟智能灌溉控制系统摘要随着农业生产水平的不断发展以及全球水资源的日趋紧张，世界各国都在积极探索行之有效的节水途径和措施。智能灌溉控制系统就是为了解决水资源不足、提高灌溉效率而发展起来的。本文研究的单片机智能灌溉控制系统，是对土壤的温湿度进行实时监控，参考实际温度值设定适宜的湿度下限值，并按照设定的湿度值进行相应的灌溉。该智能灌溉控制系统以STC89C52单片机为核心，主要由温湿度传感器DHT11模块、按键输入模块、显示模块、水泵模块等组成；软件选用C语言编程。该系统的功能是：根据土壤湿度传感器检测到的土壤湿度，若检测到的土壤湿度值低于系统所设定的最低湿度值，系统则自动启动系统，进行灌溉。通过对硬件实物的测试，系统能够比较成功的实现目标功能。【关键词】单片机；传感器；LED显示；水泵；灌溉SimulatorsmartirrigationcontrolsystembasedonsinglechipmicrocomputerAbstractAsthelevelofagriculturalproductionandthecontinuousdevelopmentofglobalshortageofwaterresources,countriesintheworldareactivelyexploringeffectivewaysandmeasuresforwaterconservation.Intelligentirrigationcontrolsysteminordertosolvetheproblemofwaterresources,improvetheefficiencyofirrigationanddeveloped.Thispaperstudiestheintelligentirrigationcontrolsystem,temperatureandhumidityinthesoilwasmonitoredinrealtime,refertotheactualtemperaturevaluesettingandhumiditylimitappropriatevalue,accordingtothesethumidityvalueforthecorrespondingirrigation.TheintelligentirrigationcontrolsystembasedonSTC89C52singlechipmicrocomputerasthecore,mainlybythetemperatureandhumiditysensorDHT11module,keyinputmodule,displaymodule,pumpmodule;softwareusedClanguageprogramming.Thefunctionofthissystemis:accordingtothesoilmoisture,soilmoisturesensortodetectsoilhumidity,ifthedetectedvalueislowerthanthelowesthumiditysystemsetting,automaticstartingsystem,irrigation.Byphysicaltesting,systemcanrealizethefunctionofrelativelysuccessful.【Keywords】Single-chipMicrocomputer；Sensor；LEDDisplay；WaterPump；Lrrigation目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc387675526"1绪论PAGEREF_Toc387675526\h11.1HYPERLINK\l"_Toc387675527"课题研究背景PAGEREF_Toc387675527\h1HYPERLINK\l"_Toc387675535"1.2课题研究的目的和意义1HYPERLINK\l"_Toc387675530"1.3国内外现状PAGEREF_Toc387675530\h2HYPERLINK\l"_Toc387675531"1.3.1国内研究现状PAGEREF_Toc387675531\h2HYPERLINK\l"_Toc387675532"1.3.2国外研究现状PAGEREF_Toc387675532\h2HYPERLINK\l"_Toc387675534"1.4本文主要工作32HYPERLINK\l"_Toc387675533"系统总体设计4HYPERLI
