距离这个项目完成到现在为止,我已经使用了9个月,它的表现很好!控制器也可以非常有效地将湿度保持在设定的水平。背景项目的主题是我想了一个很好的办法来降低我们浴室的湿度。在此之前,我有一个非常好和安静的标准普尔风扇,但它是需要我们手动操作的,有时我们会忘记打开或关闭它。所以在环顾四周之后,我发现只有少数几个商业选择。是的,你可以买一个内置控制器的风扇,但它们很贵,手动设置非常有限。一个独立的湿度控制器或开关很难找到,下降机械类开关又会非常贵。控制器描述因为我非常喜欢Arduino,所以我决定给自己做一些我需要的东西,在这种情况下,正是一个“浴室通风风扇控制器”的诞生。控制器具有以下功能和选项:测量相对湿度和温度。打开风扇(通过继电器),当湿度下降时关闭风扇。可选:在湿度下降后,风扇将保持一段可选择的时间。(把湿度再调低一点)手动打开风扇15m,30m,1,2,3,4,5,6或12小时。(对于出现异味的情况很有用)手动关闭风扇控制器系统30、1、2、4、8或12小时。(想睡觉但风扇开着?把它关掉!)将风扇控制器系统完全关闭,直到手动打开。(休假时间)用户设置存储在EEPROM中,并在复位/断电后保存。用户设置菜单:—阈值范围:40%RH~95%RH。—迟滞量范围:3%RH~9%RH。—风扇关闭延时范围:0~60min。按钮:有3个按钮,从上到下分别是:—ON/UP—OFF/DOWN—表壳侧面的SELECT—系统复位按钮控制器的显示说明在显示器的左上角,您可以看到CURRENT湿度值,每秒钟更新一次。百分比(%)符号将闪烁表示这一点。在右上角我们有湿度阈值。低于阈值,您将看到设置的HYSTERESIS值(可选)右下方显示当前的TEMPERATURE。在左下方的风扇图标将指示何时风扇被打开。如果风扇关闭延迟被激活,该图标的右边会显示一个文本'DELAY'。系统说明无事件/系统空闲:湿度和温度每秒钟都会被测量并更新一次,在测量的湿度值旁边以闪烁的“%”字符表示。传感器是非常敏感且准确。因此,它将对变化的条件作出快速和可靠的反应。事件:湿度上升等于或超过阈值:当当前湿度达到阈值时,风扇(继电器)将接通,由显示屏左下方的Fan符号指示。风扇将一直开着,直到湿度降到阈值*-滞回值*以下。所以如果阈值是70%,滞回量是5,那么风扇将在65%的相对湿度关闭。注意:显然,迟滞是非常重要的!如果不使用,你会有一个风扇开关左右的阈值。事件:湿度下降到阈值以下*减去迟滞量*:当湿度低于阈值和滞回值时,风扇关闭。例外:如果你设置了风扇关闭延迟时间,那么风扇将保持在用户确定的时间(菜单设置)手动干预措施:我故意在控制器(AFAIK)中添加了一些有用的特性。例如:厕所气味不理想,你可以手动打开风扇设定的时间。你想睡觉,但风扇开着,因为湿度太高,但风扇的噪音令人不安。你可以将系统关闭一段时间,之后它将继续测量,并在需要时打开。通风对驱除霉菌很重要,这样你就不会忘记再次打开系统。你要去度假了,把系统完全关掉。按键说明ON/UP:-系统空闲(风扇关闭):按下风扇将打开设定的时间,从15分钟开始。再次按上键,以预先确定的步骤增加风扇开机时间。(最大12小时)—SYSTEMOFF:重新打开系统—SYSTEMMANUALLYOFF:系统恢复到SYSTEMIDLE状态—MENUACTIVE:当按下数值增加时,长按快速增加数值。OFF/DOWN:—SYSTEMIDLE(风扇OFF):按下该键,系统将在设定的时间内关机,从30分钟开始关机。再次按下以增加预定步骤的关闭时间。(最大12小时)—FANISON或FANOFFDELAYactive:关闭风扇,然后与SYSTEMIDLE相同。—ANYSTATE(MENU除外):当按下按钮>1秒时,系统完全关闭,直到按下ON按钮再次打开。-MENUACTIVE:当按下数值下降时,长按快速降低数值。SELECT:—当按下1秒时,进入“userMENU”界面。(只能在IDLE/风扇关闭或风扇打开状态下使用)—设置阈值:40%RH~95%RH—迟滞量:3%RH~9%RH—风扇关闭延时:0(无延时)~60分钟。风扇继电器继电器方面我所使用的是一个好牌子的5V继电器,详情可以见示意图。我重新利用一个旧pcb与安全的情况下安装我需要的部分,并连接高电压没有风险。在风扇和230V输入之间使用5A熔断器更多图片:BathroomFanControllerv1.11://888888b.888888//888"88b888888//888.88P888888//8888888K.8888b.88888888888b.888d888.d88b..d88b.88888b.d88b.//888"Y88b"88b888888"88b888P"d88""88bd88""88b888"888"88b//888888.d888888888888888888888888888888888888888//888d88P888888Y88b.888888888Y88..88PY88..88P888888888//8888888P""Y888888"Y888888888888"Y88P""Y88P"888888888////////8888888888.d8888b.888888888//888d88PY88b888888888//888888888888888888//88888888888b.88888b.888.d88b.88888b.888888888d888.d88b.888888.d88b.888d888//888"88b888"88b888d88""88b888"88b888888P"d88""88b888888d8PY8b888P"//888.d88888888888888888888888888888888888888888888888888888888888//888888888888888Y88bd88PY88..88P888888Y88b.888Y88..88P888888Y8b.888//888"Y888888888888"Y8888P""Y88P"888888"Y888888"Y88P"888888"Y8888888///**Version1.11-Lastchange:2021-03-25WHY(whyohwhy...?)WellIlookedforagoodsolutiontokeepthehumidityleveldowninourbathroom.Wealreadyhave(already>20years)averygoodandsilentfanbutitisoperatedmanuallyandsometimesweforgottoturnitonand/oroff.Solookingaround,Ifoundthereareonlyafewoptions.Yesyoucanbuyafanwithbuildincontrollerbuttheyareexpensiveandthemanualsettingsareverylimited.Astandalonehumiditycontroller/switchwasmuchhardertofind!Ionlyfoundamechanicalswitchforjustunder100euros.ThesolutionanddescriptionAsIamveryfondoftheArduino,I(again)decidedtomakemyselfthethingsIneed,inthiscasea"BathroomFanController"(forlackofabettername)Thecontrollerhasthefollowingfunctionandoptions:MeasureRelativeHumidityandtemperature.(duh.)TurnaFanon(viaarelay)andswitchingitoffwhenthehumidityhasdropped.OPTIONAL:TheFanwillstayonforaselectabletimeafterhumidityhasdropped.(decreasethehumidityabitmore)ManuallyturntheFanONfor15m,30m,1,2,3,4,5,6or12hours.(usefulforsmellyevents...)ManuallyturntheFanControllersystemOFFfor30m,1,2,4,8or12hours.(wanttogotobedbutthenoisyfanison?turnitoff!)TurntheFanControllersystemOFFcompletelyuntilturningONmanually.(vacationtime!)UsersettingsarestoredinEEPROMandpreservedafterreset/powerfail.USERSETTINGSMENU:-Threshold:from40%RHto95%RH-Hysteresis:from3%RHto9%RH-Fanoffdelay:from0(NOdelay)to60minutes.BUTTONS:Thereare3buttons,fromtoptobottomtheseare:-ON/UP-OFF/DOWN-SELECT-onthesideofthecase:systemRESETbuttonExplanationofthedisplayofthecontroller...Atthetop-leftonthedisplayyouseetheCURRENTHUMIDITYvalue,updatedeverysecond.Thepercent(%)signwillblinktoindicatethis.onthetop-rightwehavethehumidityTHRESHOLDvalue.belowthethresholdvalueyou'llseethesetHYSTERESISvalue(optional)atthebottomright,thecurrentTEMPERATUREisdisplayed.atthebottomleftaFaniconwillindicatewhentheFanisturnedon.rightofthaticonatext'DELAY'isdisplayedifthefan-offdelayisactivated.ExplanationofthesystemNoevent/systemIDLE:Thehumidityandtemperatureismeasuredandupdatedeverysecond,indicatedbyablinking'%'characternexttothemeasuredhumidityvalue.Thesensoris*very*sensitiveandalso*very*accurate!Soitwillreactfastandreliableonchangingconditions.NOTE:IfyoudecidetouseasensorfromChinathenthiswillbeadifferentmatter.CheapANDreliable/preciseissimplynotpossible.Event:humidityhasrisenequalorabovethethreshold:Whenthecurrenthumidityreachesthethresholdvalue,theFan(relais)willswitchon,indicatedbyaFANSYMBOLatthelowerleftofthedisplay.TheFanwillstay
