摘要Arduino是比较常用于智能控制的芯片，在智能仪器、工业检测和控制、机电一体等方面应用广泛。使用Arduino可以实现温湿度全程的监测与控制，而且Arduino控制器的使用还具有易于学习掌握，性价比高等优点。基于Arduino的温湿度控制系统采用一个含有已校准数字信号输出的DHT11传感器来收集环境中的温湿度数据。经过Arduino进行数据处理，再将处理的结果通过LCD显示器进行显示。当环境中的参数达到预先设定的临界值时，报警系统中的无源蜂鸣器就会自动鸣响报警。采用Arduino设计的温湿度控制系统，可以精确的反应环境的温度以及湿度的变化情况。完成升温、降温等一列智能控制行为。在一定的温度波动范围内保持恒温状态。将这样智能系统应用到现代温室种植当中，可以为农作物的生长提供较为适宜的生长环境。对于一些特殊的农业生产诸如大棚种植和花卉种植等必须使用温湿度装置对其进行监控使其保持恒定环境。本系统可以及时、精确的反映和控制环境中的温湿度的变化。关键词：Arduino；DHT11；传感器；液晶显示器；温湿度；ABSTRACTArduinoisrelativelycommonlyusedinthecontrolchip,smartinstrumentation,industrialinspectioncontrol;mechatronicsachievedimpressiveresultshasbeenwidelyapplied.alsoalotofitsstrengthasthetemperatureandhumiditycontrolsystem.AbletoachieveautomaticcontroloftemperatureandhumiditythroughoutArduino,theArduinoiseasytolearnandmasterthehighcost-effective.ThispaperdesignsatemperatureandhumiditycontrolsystembasedonArduino,,thesystemusesacontainingcompositesensorDHT11digitaltemperatureandhumiditycalibrationofdigitalsignaloutputtotemperatureandhumiditydataacquisitionintheenvironment..AfterArduinotreatment,andthetreatmentresultsthroughtheLCDdisplaydisplay.Whentheparametersintheenvironmentreachesthecriticalvalue,thealarmwillsoundthealarmsystem.UseaArduino-typemicro-controllerdesigntemperatureandhumiditycontrolsystemfor,instantaccuratereactiongreenhousetemperatureandmoderatechanges.Complete,suchasthetemperaturewascooledtoaspecifictemperature,raisedtoaspecifictemperature.Maintainconstanttemperatureandothercontrolinthevolatilitytemperaturerange,humiditycontrolisalsotrue.Theapplicationofthissystemtothegreenhousewhichisnodoubtthatprovidesamoresuitableenvironmentforvegetationgrowth.Forgreenhousecultivationandflowergarden,flowercultivation,youmustinstallcertainenvironmentaltemperatureandhumiditydevicemonitor.Thissystemcanbetimely,accuratereflectionoftheindoortemperatureandhumiditychanges,abletomeettherequirementsofthetemperatureandhumiditycontrol.Keywords:Arduino;DHT11;Sensor;LCD;TemperatureandHumidity;目录第一章绪论.........................................11.1课题背景..........................................11.2研究目的及意义....................................11.2.1生活环境与温湿度的关系.......................11.2.2温湿度检测的意义.............................21.3国内外发展历程和状况..............................3第二章Arduino理论基础..............................52.1单片机-Arduino的核心器件.........................52.1.1单片机的概念.................................52.1.2单片机的作用.................................52.1.3Arduino的定义...............................62.1.4Arduino的优势...............................62.2Arduino开发工具介绍..............................72.3Arduino语言......................................82.4本章总结..........................................9第三章系统整体设计.................................103.1方案论证.........................................103.1.1系统主要功能................................103.1.2系统的工作原理简...
