基于单片机的智能浇花系统的设计及其实现.doc

基于单片机智能浇花系统设计和实现摘要伴随社会发展，人民越来越重视环境质量。养殖花卉成了首要选择，在家养殖能够陶怡情操，丰富生活。同时花卉能够经过光合作用吸收二氧化碳释放氧气同时还能够净化空气，而且花卉还能够吸收有毒物质比如刚装修房屋里苯、甲醛等。所以越来越多人喜爱养殖花卉。本文设计了一个智能湿度感应浇花系统。系统以单片机AT89S52为控制芯片，开启浇花之前先有蜂鸣器报警，按时按量供水是完成天天在限定时间自动开启水泵浇花，根据多种花卉所需水量差异，使用一个按钮装置来控制给水时间，也就是电磁阀开启和闭合时间，其它时间水泵不转，不会有水流通供给补水；根据温度、湿度来严格控制给水关键用到是SLHT5-1土壤温度、湿度传感器，假如传感器检测温度、湿度全部达不到要求要求，就开始浇花，达成了要求温度、湿度就停止浇花。该系统既能按时、按量给花卉浇水，还能够为节省水资源，从而让花卉愈加好生长。关键词：单片机；智能浇花系统；传感器；AbstractWiththedevelopmentofsociety,peoplepaymoreandmoreattentiontoenvironmentalquality.Flowercultivationhasbecomethefirstchoice,infarmingcanTaoYisentiment,enrichlife.Atthesametime,flowerscanabsorbcarbondioxidethroughphotosynthesisreleaseoxygenalsocanpurifytheair,andthefloweralsocanabsorbtoxicsubstancessuchasjustdecorationhouseofbenzeneandformaldehyde.Somoreandmorepeopleliketobreedflowers.Thispaperdesignsakindofintelligenthumiditysensingwateringsystem.ThesystemwithAT89S52singlechipcomputerascontrolchip,firststartedwateringtheflowersbeforethebuzzeralarm,timingquantitativewateringistopumpwatertheflowerseverydaytoopenautomaticallyataspecifiedtime,accordingtothedifferentflowersneeddifferentquantityofwater,withabuttontosetthewateringtimelength,i.e.,thesolenoidvalveopentime,therestofthetimethepumpdoesnotturnwatercannotflowthrough,accordingtowatertheflowers;humiditycontrolistouseaSLHT5-1soilmoisturesensor,whenthedetectedhumiditydidnotreachthesettinghumidity,begantowatertheflowers,tothesettinghumiditystopwatering.Thissystemcannotonlyontime,accordingtotheamountofgiveflowerwatering,canalsosavewaterresources,soastomakeflowersgrowbetter.Keyword:MCU;intelligentwateringsystem;sensor目录TOC\o"1-3"\h\uHYPERLINK\l_Toc112111、绪论PAGEREF_Toc112111HYPERLINK\l_Toc54171.1选题目标及意义PAGEREF_Toc54171HYPERLINK\l_Toc244321.2中国市场发展现实状况PAGEREF_Toc244321HYPERLINK\l_Toc127061.3研究方法和手段PAGEREF_Toc127062HYPERLINK\l_Toc70192、基于单片机智能浇花系统PAGEREF_Toc70194HYPERLINK\l_Toc88692.1系统组成部分PAGEREF_Toc88694HYPERLINK\l_Toc42.2系统工作原理PAGEREF_Toc44HYPERLINK\l_Toc69983、系统硬件
