想請教如何把WIFI模組的程式融入於PM2.5 SENSOR+DHT11
各位arduino的前輩，我想請教有關WIFI模組的程式融入於PM2.5 SENSOR+DHT11，其WIFI程式碼如下：#include <SoftwareSerial.h>
#define _baudrate 9600
#define _rxpin 9
#define _txpin 10
SoftwareSerial debug( _rxpin, _txpin ); // RX, TX
//*-- IoT Information
#define SSID "aerosol"
#define PASS "power725"
#define IP "184.106.153.149" // ThingSpeak IP Address: 184.106.153.149
// 使用 GET 傳送資料的格式
// GET /update?key=&field1=&filed2=...;
String GET = "GET /update?key=UR0WZRMIAUXQVUBI";
void setup() {
Serial.begin( _baudrate );
debug.begin( _baudrate );
sendDebug("AT");
Loding("sent AT");
connectWiFi();
}
void loop() {
delay(5000); // 60 second
SentOnCloud( String(5), String(9) );
}
boolean connectWiFi()
{
debug.println("AT+CWMODE=1");
Wifi_connect();
}
void SentOnCloud( String T, String H )
{
// 設定 ESP8266 作為 Client 端
String cmd = "AT+CIPSTART=\"TCP\",\"";
cmd += IP;
cmd += "\",80";
sendDebug(cmd);
if( debug.find( "Error" ) )
{
Serial.print( "RECEIVED: Error\nExit1" );
return;
}
cmd = GET + "&field1=" + T + "&field2=" + H +"\r\n";
debug.print( "AT+CIPSEND=" );
debug.println( cmd.length() );
if(debug.find( ">" ) )
{
Serial.print(">");
Serial.print(cmd);
debug.print(cmd);
}
else
{
debug.print( "AT+CIPCLOSE" );
}
if( debug.find("OK") )
{
Serial.println( "RECEIVED: OK" );
}
else
{
Serial.println( "RECEIVED: Error\nExit2" );
}
}
void Wifi_connect()
{
String cmd="AT+CWJAP=\"";
cmd+=SSID;
cmd+="\",\"";
cmd+=PASS;
cmd+="\"";
sendDebug(cmd);
Loding("Wifi_connect");
}
void Loding(String state){
for (int timeout=0 ; timeout<10 ; timeout++)
{
if(debug.find("OK"))
{
Serial.println("RECEIVED: OK");
break;
}
else if(timeout==9){
Serial.print( state );
Serial.println(" fail...\nExit2");
}
else
{
Serial.print("Wifi Loading...");
delay(500);
}
}
}
void sendDebug(String cmd)
{
Serial.print("SEND: ");
Serial.println(cmd);
debug.println(cmd);
}
想融入先前寫好的PM2.5 SENSOR+DHT11，程式碼如下:

//Serial.print(HT);
dustDensity = 0;
mean_v0=0;
float vs=170;
for (int i = 0; i <= 29; i++) {
digitalWrite(ledPower, LOW);

// Serial.println(voMeasured);

delay(18);
};
mean_v0=mean_v0/30;
mean_pm = dustDensity / 30.0;
snprintf(pm, sizeof(pm), "%04d", mean_pm);

myFile.print(", ");

myFile.print(pm_SD);
myFile.println("");
myFile.close();
};
分開時都可以正常運行，但合在一起卻卡在WIFI 不斷LOADING，
請各位前輩不吝指點，感謝 因為不知道你用那個版本 ARDUINO,
我猜應該是你的 WIFI 的 TX 和 SD 的 CS 衝到了
1)WIFI模組
#define _txpin 10
2) PM2.5 SENSOR+DHT11 中間有一行
pinMode(10, OUTPUT);
