空調(diào)（空調(diào)）曾經(jīng)被認(rèn)為是奢侈品，只能在大酒店，電影院，餐館等中找到...但是，現(xiàn)在幾乎每個(gè)人都在家里有空調(diào)來(lái)度過夏天/冬天，而那些擁有它的人擔(dān)心一件共同的事情。這就是他們的高耗電量和充電器。在這個(gè)項(xiàng)目中，我們將制作一個(gè)小型的自動(dòng)溫度控制電路，該電路可以通過根據(jù)室溫自動(dòng)改變交流溫度來(lái)最小化充電器。通過定期改變?cè)O(shè)定溫度，我們可以避免使交流電長(zhǎng)時(shí)間以較低的溫度值工作，從而使其消耗更少的功率。

我們大多數(shù)人都會(huì)遇到這樣一種情況，即我們必須在一天中的不同時(shí)間將空調(diào)的設(shè)定溫度更改為不同的值，以使我們始終保持舒適。為了自動(dòng)化此過程，該項(xiàng)目使用溫度傳感器（DHT11），該傳感器讀取房間的當(dāng)前溫度，并根據(jù)該值，它將通過類似于AC遙控器的紅外發(fā)射器向AC發(fā)送命令。AC 將對(duì)這些命令做出反應(yīng)，就像它對(duì)遙控器做出反應(yīng)一樣，從而調(diào)節(jié)溫度。隨著房間溫度的變化，Arduino還會(huì)調(diào)整空調(diào)的設(shè)定溫度，以您想要的方式保持您的溫度。聽起來(lái)很酷吧?...讓我們看看如何構(gòu)建一個(gè)。

所需材料：

阿杜伊諾超級(jí) 2560

TSOP1738 （HS0038）

紅外燈

DHT11 溫度/濕度傳感器

任何顏色 LED 和 1K 電阻器（可選）

面包板

連接線

工作方法：

我們家中用于控制電視、家庭影院、空調(diào)等的所有遙控器都在紅外發(fā)射器的幫助下工作。紅外發(fā)射器只不過是一個(gè)紅外 LED，可以通過重復(fù)脈沖來(lái)沖擊信號(hào);該信號(hào)將由電子設(shè)備中的接收器讀取。對(duì)于遙控器上的每個(gè)不同按鈕，將發(fā)出一個(gè)獨(dú)特的信號(hào)，該信號(hào)在接收器讀取后用于執(zhí)行特定的預(yù)定義任務(wù)。如果我們能夠讀取從遙控器發(fā)出的信號(hào)，那么我們可以在需要執(zhí)行該特定任務(wù)時(shí)使用紅外 LED 模擬相同的信號(hào)。

TSOP是一種紅外接收器，可用于解碼來(lái)自遙控器的信號(hào)。該接收器將與Arduino接口，為每個(gè)按鈕發(fā)送信號(hào)，然后IR LED將與Arduino一起使用，以在需要時(shí)模擬信號(hào)。這樣，我們就可以使用Arduino控制AC。

現(xiàn)在，剩下的就是使用 DHT11 讀取溫度值，并使用 IR 信號(hào)相應(yīng)地指示 AC。為了使項(xiàng)目看起來(lái)更具吸引力和用戶友好性，我還添加了一個(gè)OLED顯示屏，可以顯示當(dāng)前的溫度，濕度和AC設(shè)定溫度。

交流遙控器的工作：

在我們進(jìn)入項(xiàng)目之前，請(qǐng)花一些時(shí)間并注意您的交流遙控器的工作原理。與電視、DVD 紅外遙控器相比，交流遙控器的工作方式略有不同。遙控器上可能只有 10-12 個(gè)按鈕，但它們將能夠發(fā)送許多不同類型的信號(hào)。這意味著遙控器不會(huì)每次為同一按鈕發(fā)送相同的代碼。例如，當(dāng)您使用向下按鈕降低溫度使其為 24°C（攝氏度）時(shí)，您將獲得帶有一組數(shù)據(jù)的信號(hào)，但是當(dāng)您再次按下它以設(shè)置 25°C 時(shí)，您將不會(huì)獲得相同的數(shù)據(jù)，因?yàn)闇囟痊F(xiàn)在是 25 而不是 24。同樣，25 的代碼也會(huì)因不同的風(fēng)扇速度、睡眠設(shè)置等而異。因此，我們不要擺弄所有選項(xiàng)，而只是將溫度值與其他設(shè)置的恒定值集中在一起。

另一個(gè)問題是每次按下按鈕發(fā)送的數(shù)據(jù)量，普通遙控器發(fā)送 24 位或 48 位，但交流遙控器最多可以發(fā)送 228 位，因?yàn)槊總€(gè)信號(hào)都包含大量信息，如溫度、風(fēng)扇速度、睡眠時(shí)間、擺動(dòng)風(fēng)格等。這就是為什么我們需要Arduino Mega以獲得更好的存儲(chǔ)選項(xiàng)的原因。

電路圖及說(shuō)明：

幸運(yùn)的是，這個(gè)自動(dòng)交流溫度控制項(xiàng)目的硬件設(shè)置非常簡(jiǎn)單。您可以簡(jiǎn)單地使用面包板并進(jìn)行連接，如下所示。

下表還可用于驗(yàn)證連接。

連接完成后，它應(yīng)該如下所示。我使用面包板來(lái)整理東西，但您也可以直接將公對(duì)母線連接到所有組件

解碼交流遠(yuǎn)程信號(hào)：

控制交流電的第一步是使用 TSOP1738解碼交流遙控紅外代碼。按照電路圖中所示進(jìn)行所有連接，并確保已安裝所有提到的庫(kù)?，F(xiàn)在打開示例程序“IRrecvDumpV2”，可以在文件 -> 示例 -> IRremote -> IRrecvDumpV2 中找到。將程序上傳到Arduino Mega并打開串行監(jiān)視器。

將遙控器指向 TSOP 并按任意按鈕，對(duì)于您按下的每個(gè)按鈕，信號(hào)將由 TSOP1738 讀取，由 Arduino 解碼并顯示在串行監(jiān)視器中。對(duì)于遙控器溫度的每次變化，您將獲得不同的數(shù)據(jù)。保存此數(shù)據(jù)，以便我們將在主程序中使用它。您的串行監(jiān)視器將看起來(lái)像這樣，我還顯示了保存復(fù)制數(shù)據(jù)的Word文件。

屏幕截圖顯示了將我的交流遙控器的溫度設(shè)置為 26°C 的代碼。根據(jù)您的遙控器，您將獲得一組不同的代碼。同樣，復(fù)制所有不同溫度水平的代碼。

主要Arduino程序：

完整的Arduino主程序可以在此頁(yè)面底部找到，但您不能使用相同的程序。您必須更改我們剛剛從上面的示例草圖中獲得的信號(hào)代碼值。打開Arduino IDE上的主程序，然后向下滾動(dòng)到下面顯示的該區(qū)域，您必須將數(shù)組值替換為為遙控器獲得的值。

請(qǐng)注意，我使用了 10 個(gè)陣列，其中兩個(gè)用于打開和關(guān)閉交流電，而其余 8 個(gè)用于設(shè)置不同的溫度。例如，Temp23 用于在交流電上設(shè)置 23°C，因此請(qǐng)使用該陣列中的相應(yīng)代碼。完成后，您只需將代碼上傳到Arduino并將其放在AC對(duì)面，即可享受涼風(fēng)。

代碼的解釋如下，首先我們必須使用DHT1溫度傳感器讀取溫度和濕度并將其顯示在OLED上。這是通過以下代碼完成的。

DHT.read11(DHT11_PIN); //Read the Temp and Humidity
Measured_temp = DHT.temperature + temp_error;
Measured_Humi = DHT.humidity;

// text display tests
display.setTextSize(1);
display.setTextColor(WHITE);
display.setCursor(0,0);
display.print("Temperature: "); display.print(Measured_temp);display.println("C");
display.setCursor(0,10);
display.print("Humidity: "); display.print(Measured_Humi);display.println("%");
一旦我們知道房間的溫度，我們只需要將其與所需的值進(jìn)行比較。這個(gè)期望值是一個(gè)常量值，在我的程序中設(shè)置為 27°C（攝氏度）。因此，基于此比較，我們將設(shè)置相應(yīng)的交流溫度，如下所示

if (Measured_temp == Desired_temperature+3) //If AC is ON and measured temp is very high than desired
{
irsend.sendRaw(Temp24, sizeof(Temp24) / sizeof(Temp24[0]), khz); delay(2000);//Send signal to set 24*C
AC_Temp = 24;
}
當(dāng)測(cè)量溫度為 30°C 時(shí)，此處的 AC 將設(shè)置為 24°C（因?yàn)樗铚囟葹?27）。同樣，我們可以創(chuàng)建許多 If 循環(huán)，以根據(jù)測(cè)量的溫度設(shè)置不同的溫度級(jí)別，如下所示。

if (Measured_temp == Desired_temperature-1) //If AC is ON and measured temp is low than desired value
{
irsend.sendRaw(Temp28, sizeof(Temp28) / sizeof(Temp28[0]), khz); delay(2000);//Send signal to set 28*C
AC_Temp = 28;
}

if (Measured_temp == Desired_temperature-2 ) //If AC is ON and measured temp is very low than desired value
{
irsend.sendRaw(Temp29, sizeof(Temp29) / sizeof(Temp29[0]), khz); delay(2000);//Send signal to set 29*C
AC_Temp = 29;
}

if (Measured_temp == Desired_temperature-3 ) //If AC is ON and measured temp is very very low desired value
{
irsend.sendRaw(Temp30, sizeof(Temp30) / sizeof(Temp30[0]), khz); delay(2000);//Send signal to set 30*C
AC_Temp = 30;
}

自動(dòng)交流溫控系統(tǒng)工作原理：

當(dāng)您的代碼和硬件準(zhǔn)備就緒時(shí)，將代碼上傳到您的主板，您應(yīng)該注意到 OLED 顯示與此類似的內(nèi)容。

現(xiàn)在將電路放在空調(diào)的對(duì)面，您會(huì)注意到空調(diào)的溫度會(huì)根據(jù)室溫進(jìn)行控制。

您可以調(diào)整程序以執(zhí)行任何所需的操作;您所需要的只是從示例草圖中獲取的代碼。希望您了解這個(gè)自動(dòng)溫度控制器項(xiàng)目，并喜歡構(gòu)建非常相似的東西。
