軟體

Arduino IDE
Seeed Studio (https://github.com/Seeed-Studio/PIR_Motion_Sensor, http://www.seeed.cc/project_detail.html?id=284)
Cayenne API (https://mydevices.com/cayenne/docs/#using-cayenne-library)

使用離線程式測試硬體

完成硬體安裝後，現在可以運行離線程式進行測試。這是“離線”模式，系統尚未連接到Internet。我們馬上就進行測試。離線程式將執行下列功能：

遙控射極器（在示例中使用頻道D）打開/斷路警報。如果遙控射極器打開，綠色 LED將亮起，蜂鳴器將發出一次嗶嗶聲。
PIR感測器將檢測行動情況。如果檢測到行動，藍色 LED 將亮起。
當警報聲響起並檢測到行動時，紅色 LED將亮起，蜂鳴器將熄滅。
同樣，當警報聲響起（即綠色 LED亮起）且熱量高於設定目標時，紅色 LED將亮起，蜂鳴器將熄滅。

注：

若想斷路警報聲，用戶只需再次按遙控射極器上的頻道D。綠色 LED將熄滅，蜂鳴器將發出兩次嗶嗶聲。

若需查看溫度和氣壓的值，請將USB電線從Arduino連接到PC。然後，進入Arduino IDE並按一下工具 → 序列監視器。

現在可以上傳程式。進行編譯以前，請確保已安裝所有必需的程式館。

準備線上連接

創建一個myDevices帳戶！您可以通過以下連結註冊並創建一個新帳戶：https://mydevices.com/cayenne/signup/

如果您已經擁有帳戶，請隨意使用自己的帳戶。

圖1. 註冊頁面 – https://mydevices.com/cayenne/signup/

然後選擇Arduino作為本專案的裝置。

圖2. 選擇本專案所需的Arduino裝置

閱讀文檔並通過以下網站安裝Cayenne程式館：

https://mydevices.com/cayenne/docs/#using-cayenne-library

然後繼續下一步，在新網頁中連接到Arduino。選擇Arduino Mega和WiFi Shield。選定這兩項後，您將收到裝置的“身份驗證口令”。務必複製此口令並將其保存於某處。在下一個程式中需要用到此口令。

char token[] = “zzzzzzz”; // Cayenne authentication token

圖3. 選擇Arduino Mega和WiFi Shield

圖4. 創建感測器微件

創建微件

我們可以為PIR感測器、觸發狀態和警報開/關狀態創建微件。

為此，必須按一下 “添加新…” ，然後按一下 “裝置/微件”。然後轉到 “感測器” 類別並按一下 “通用”。在“通用”下，有2個輸入選項：類比輸入和數位輸入。選擇 “數位輸入”。進入“數位輸入”設定頁面後，將連接設定為“虛擬”和“V1”（在下方）。請勿忘記按一下 步驟 1 和 步驟 2。

V2和V4微件也按相同步驟操作。請使用下表作為參考：

虛擬頻道號	微件名稱	選擇微件	選擇圖示/顯示	連接至
V1	PIR 感測器	0/1 2 狀態	顯示值	PIR 感測器 – 藍色 Led
V2	觸發狀態	0/1 2 狀態	顯示值	觸發開關 – 紅色 Led
V4	警報狀態開/關	0/1 2 狀態	圖示指示燈	遠端開關

代碼中使用的虛擬引腳分配如下：

#define VIRTUAL_PIN1 V1 // PIR感測器的虛擬引腳 – 藍色 Led

#define VIRTUAL_PIN2 V2 // 觸發開關的虛擬引腳 – 紅色 Led

#define VIRTUAL_PIN4 V4 // 遠端開關的狀態

當PIR感測器檢測到發生行動時，V1將開啟（顏色變為綠色）；藍色LED也將亮起。
當觸發狀態開啟時，V2將開啟（顏色變為綠色）；當警報開啟且PIR感測器檢測到發生行動時，紅色LED也將亮起。
通過遙控射極器或線上/應用程式開啟警報狀態時，V4將開啟（顏色變為綠色）

接下來為線上/應用程式開關功能創建一個微件。

轉至 “添加新…” ，然後按一下 “裝置/微件”。這次選擇 “執行器” ，然後選擇 “通用”。選擇 “數位輸出” ，然後在“連接”下選擇“虛擬”。在“Pin”下，選擇“V3”。

圖5. 創建線上/應用程式開關功能的微件

使用下表作為參考：

虛擬頻道號	微件名稱	選擇微件	選擇圖示/顯示	連接到
V3	線上/應用程式開關	按鈕	圖示鎖定	線上/應用程式開關 — 綠色 LED

按一下微件（在網站/應用程式上）時，V3將開啟（顏色變為紫色）。當V3開啟時，綠色LED也會亮起。因此，該虛擬開關與遙控射極器功能相同。但是，通過此虛擬交換機啟動時會有一段延時。在下一程式中以下代碼將會引用引腳V3。

#define VIRTUAL_PIN3 V3 // 線上開關 – 綠色 led

然後需要創建溫度和壓力感測器的微件。和前面一樣，點擊 “添加新…” 和 “裝置/微件”。然後選擇 “感測器” 和 “通用” ，然後選擇 “類比輸入”。連接後，選擇“虛擬”和“V5”進行引腳選擇。

圖6. 創建溫度和壓力感測器的微件

對V6執行相同操作並使用下表作為參考：

虛擬頻道號	微件名稱	選擇微件	選擇單位	連接到
V5	溫度(℃)	測量精度	有效位數 – 小數點後2位	溫度感測器
V6	氣壓(hPa)	測量精度	有效位數 – 小數點後2位	大氣壓力感測器

在下一程式中以下代碼將會引用引腳V5和V6。

#define VIRTUAL_PIN5 V5 // 溫度感測器

#define VIRTUAL_PIN6 V6 // 氣壓感測器

如果上述所有步驟都正確完成，您將看到如圖7所示的頁面。

圖7. 微件的顯示

最後一步是啟用電子郵件通知功能（觸發警報時）。為此，請按一下“觸發器狀態”微件上的設定符號，然後選擇“觸發器”。

圖8. 創建電子郵件觸發器

然後，您將進入以下頁面（圖9）。在“添加自訂收件人”中鍵入您的電子郵寄位址，然後按一下“發送電子郵件”。

圖9. 設定電子郵件通知

myDevices設定到此結束！

測試線上程式

以上已經完成了與家庭保全系統的線上連接設定。運行最終程式前可以先測試線上程式。

上傳以下程式。確保已安裝適用於Arduino的Cayenne程式館。該程式用於執行簡單的功能（即顯示溫度和氣壓值）。正確運行時，溫度和氣壓微件將改變顏色（綠色和橙色），相應數值顯示於微件的底部。

以下幾種方法可以測試程式是否正常運行。

檢查觸發警報時是否發送電子郵件。您應收到如圖10所示的電子郵件。

圖10. 觸發警報時收到的電子郵件通知

檢查您是否可以看到溫度和氣壓圖。如需顯示圖形，請按一下視窗微件右上角的圖形符號。

圖11. 感測器的圖形符號的顯示

然後還會顯示圖表：

下載智慧手機APP

如前所述，無論何時何地只要您能連接WiFi，您就可以24/7全天候對保全系統進行監控。您可以在網站上或通過Cayenne手機APP進行監控。您可以在智慧手機上直接下載Cayenne APP。進入App Store（適用於iPhone）或Google Play商店（適用於Android）並搜索Cayenne然後就能下載。
