該項(xiàng)目具有檢測(cè)室內(nèi)環(huán)境數(shù)據(jù)和發(fā)送電子郵件、開(kāi)燈按鈕、體感照明屏等功能。

經(jīng)過(guò)不斷的踩坑學(xué)習(xí)，初代簡(jiǎn)易智能家居中控系統(tǒng)已經(jīng)完成，大部分功能已經(jīng)完成，但是有些功能WIO終端沒(méi)有實(shí)現(xiàn)。一方面是因?yàn)榇a量太大，會(huì)給WIO終端帶來(lái)很大的“壓力”；另一方面，我的技術(shù)還不夠，還得繼續(xù)學(xué)習(xí)，尋找解決方案。

首先介紹一下我最初的想法：

WIO終端是一款高度集成的開(kāi)發(fā)板。它配備了液晶顯示屏、三個(gè)按鈕、一個(gè)五向開(kāi)關(guān)、麥克風(fēng)、揚(yáng)聲器、加速度傳感器、紅外發(fā)射器等，甚至可以與樹(shù)莓派和 Jetson nano 結(jié)合使用。作為家居的“大腦”，這些硬件非常實(shí)用。因此，在智能家居的中控系統(tǒng)中，我選擇WIO終端作為這個(gè)系統(tǒng)的核心。

未來(lái)，家里應(yīng)該有一個(gè)智能管家。這個(gè)智能管家就是我現(xiàn)在做的簡(jiǎn)單版。有了它，您就可以在家中獲取準(zhǔn)確實(shí)時(shí)的溫度、濕度、光照強(qiáng)度等數(shù)據(jù)。不僅如此，它還像一個(gè)“萬(wàn)能”遙控器，可以幫助你控制家中的電器。當(dāng)然，它應(yīng)該像智能音箱一樣，能夠理解我們給它的指令并響應(yīng)我們！

提前準(zhǔn)備
在這個(gè)項(xiàng)目的過(guò)程中，我第一次使用了開(kāi)發(fā)板WIO終端：

不知為何，在WIO終端上使用grow-temperature 濕度壓力氣體傳感器時(shí)，接收不到數(shù)據(jù)，只好轉(zhuǎn)身實(shí)現(xiàn)：

使用Django搭建一個(gè)簡(jiǎn)單的數(shù)據(jù)中心（基于Grove——溫度濕度壓力氣體傳感器）

重回正軌，實(shí)現(xiàn)數(shù)據(jù)展示的主要功能：

使用WIO終端通過(guò)HTTP請(qǐng)求獲取并顯示傳感器實(shí)時(shí)數(shù)據(jù)

下一步就是完善其他三個(gè)功能，我主要通過(guò)python實(shí)現(xiàn)

完善系統(tǒng)功能
前面我簡(jiǎn)單提到了一些WIO終端上沒(méi)有實(shí)現(xiàn)的功能的原因，具體原因我沒(méi)有細(xì)說(shuō)。畢竟剛開(kāi)始做，所以打算先實(shí)現(xiàn)功能。至于實(shí)現(xiàn)方式，我想在二代系統(tǒng)中改進(jìn)一下

通過(guò) WIO 端子輸出狀態(tài)
我要表達(dá)的狀態(tài)是讀取可配置按鈕的狀態(tài)（是否按下按鈕）和麥克風(fēng)的數(shù)據(jù)（數(shù)據(jù)也可以代表狀態(tài)）

對(duì)于WIO終端來(lái)說(shuō)，簡(jiǎn)單的輸出這些數(shù)據(jù)還是比較簡(jiǎn)單的

補(bǔ)充 setup() 中的管腳定義：

pinMode(WIO_MIC, INPUT);
pinMode(WIO_KEY_A, INPUT_PULLUP);
pinMode(WIO_KEY_B, INPUT_PULLUP);
pinMode(WIO_KEY_C, INPUT_PULLUP);

補(bǔ)充loop()中的if條件語(yǔ)句：

int val_first = analogRead(WIO_MIC);
int val_next = analogRead(WIO_MIC);

if (abs(val_first - val_next) >= 100){
Serial.println("send message!");
}
if (digitalRead(WIO_KEY_A) == LOW) {
Serial.println("A Key pressed");
}
if (digitalRead(WIO_KEY_B) == LOW) {
Serial.println("B Key pressed");
}
if (digitalRead(WIO_KEY_C) == LOW) {
Serial.println("C Key pressed");
}
當(dāng)WIO終端連接PC時(shí)，PC會(huì)讀取串口的數(shù)據(jù)，并在讀取相應(yīng)的輸出時(shí)采取相應(yīng)的動(dòng)作

至此，我們已經(jīng)完成了關(guān)于 Arduino 的所有代碼。整理一下代碼，分享給大家。

接下來(lái)我們來(lái)看看Python的具體實(shí)現(xiàn)

使用Python讀取串口數(shù)據(jù)并做出相應(yīng)決策

web端增加了保存數(shù)據(jù)的功能

因?yàn)槲倚枰l(fā)送郵件，所以我先將傳感器接收到的數(shù)據(jù)存儲(chǔ)在一個(gè)TXT文本文件中。發(fā)送郵件時(shí)，我可以直接發(fā)送這個(gè)文本文件

在視圖中在 py 中：

def index(request):
datas = getDatas()
content = {
'temperature':datas[0],
'pressure':datas[1],
'humidity':datas[2],
'gas':datas[3],
'updataTime':datas[4],
}
jsonData = json.dumps(content)
with open("D:\TemperatureHumidityPressureGasData.txt", "w") as fp:
fp.write(jsonData)
return HttpResponse(jsonData)

主要變化是：

with open("D:\TemperatureHumidityPressureGasData.txt", "w") as fp:
fp.write(jsonData)

文件存放路徑可以修改為自己的路徑

打開(kāi)文本文件，看能否保存成功：

通過(guò)紅外模塊控制小夜燈

小夜燈可以遙控控制：

因?yàn)閃IO終端沒(méi)有紅外解碼功能，所以我又買(mǎi)了一個(gè)紅外模塊，編解碼合二為一。當(dāng)然，我還需要一個(gè)usb-ttl串口轉(zhuǎn)換器：

其實(shí)這個(gè)想法很簡(jiǎn)單。讀取遙控器對(duì)應(yīng)按鍵發(fā)送的數(shù)據(jù)，然后用紅外模塊發(fā)送出去

可以使用串口調(diào)試助手進(jìn)行解碼，更方便：

串行端口發(fā)送它接收到的任何內(nèi)容。收貨時(shí)最好找個(gè)比較暗的地方多試幾次

未來(lái)的想法

目前的系統(tǒng)只是一個(gè)非常簡(jiǎn)單的第一代版本。往后我們可能會(huì)考慮使用云平臺(tái)存儲(chǔ)傳感器采集的溫度、濕度、光照強(qiáng)度、紫外線強(qiáng)度等數(shù)據(jù)，制作一個(gè)APP，讓用戶出門(mén)在外就可以知道家里的情況。
