基于单片机的智能浇花系统的设计与实现摘要随着社会的发展，人民越来越注重环境质量。养殖花卉成了首要选择，在家养殖可以陶怡情操，丰富生活。同时花卉可以通过光合作用吸收二氧化碳释放氧气同时还可以净化空气，而且花卉还可以吸收有毒物质例如刚装修的房屋里的苯、甲醛等。因此越来越多的人喜欢养殖花卉。本文设计了一种智能湿度感应浇花系统。系统以单片机AT89S52为控制芯片，启动浇花之前先有蜂鸣器报警，按时按量的供水是完成每天在限定的时间自动启动水泵浇花，按照各种花卉所需水量的差别，使用一个按钮装置来控制给水的时间，也就是电磁阀开启和闭合的时间，其余时间水泵不转，不会有水流通供给补水；按照温度、湿度来严格控制给水主要用到的是SLHT5-1土壤温度、湿度传感器，如果传感器检测温度、湿度都达不到规定的要求，就开始浇花，达到了规定的温度、湿度就停止浇花。该系统既能按时、按量的给花卉浇水，还可以为节约水资源，从而让花卉更好的生长。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选题目的及意义PAGEREF_Toc54171HYPERLINK\l_Toc244321.2国内市场发展现状PAGEREF_Toc244321HYPERLINK\l_Toc127061.3研究方法和手段PAGEREF_Toc127062HYPERLINK\l_Toc70192、基于单片机的智能浇花系统PAGEREF_Toc70194HYPERLINK\l_Toc88692.1系统组成部分PAGEREF_Toc88694HYPERLINK\l_Toc200042.2系统
