Question

所以到目前为止，我的代码是让我的arduino能够使用以太网发送加速度计和陀螺仪数据，但我无法弄清楚如何使其无线化。

这是我到目前为止所拥有的：

`
＃包括＃包括的#include

Byte mac[] = { 0x00, 0Xaa, 0xbb, 0xcc, 0xde 0x01 }; // Reserved Mac Address
 EthernetClient client;

 #define DHTPIN 2 // SENSOR PIN
    #define DHTTYPE DHT11 // SENSOR TYPE
 DHT dht(DHTPIN, DHTTYPE);

 long previousMillis = 0;
 unsigned long currentMillis= 0;
 long interval = 250000; //READING INTERVAL

 int t = 0; // TEMPERATURE VAR
 int h = 0; // HUMIDITY VAR
 String data;

 Void setup() {
 Serial.begin(115200);
      If (Ethernet.begin(mac) == 0) {
 Serial.println(“Failed to configure Ethernet using DHCP”);
 }

 dht.begin();
 delay(10000); // GIVE THE SENSOR SOME TIME TO START

  h = (int) dht.readHumidity();
  t = (int) dht.readTemperature();

  data = “”;
 }

void loop(){

currentMillis = millis();
   if(currentMillis – previousMillis > interval) {    //READ ONLY ONCE PER           INTERVAL
  previousMillis = currentMillis;
    h = (int) dht.readHumidity();
   t = (int) dht.readTemperature();
  }
     data = “templ=” + t + “&hum1=” + h;          //THIS IS FOR PRINTING DATA TO WEBPAGE

   if (client.connect(www.*****.*************.com,80)) {       //REPLACE WITH SERVER ADDRESS
    client.println(“POST /add.php HTTP/1.1”);
   client.println(“Host: *****.*************.com,80”);         //SERVER ADDRESS HERE TOO
client.println(“Content-Type: application/x-www-form-urlencoded”);
 client.print(“Content-Length: “);
client.println(data.length());
 client.println();
 client.print(data);
 }

If (client.connected()) {
client.stop();  //Disconnect from the server
}

delay(300000);   //Wait five minutes before sending again

}

`

谢谢

Answer 1

你需要一个像ESP8266这样的WiFi模块。

你也可以单独使用它（没有arduino）因为它是带有io引脚的完整soc。

Answer 2

对于小范围，您可以使用Xbee模块或蓝牙防护。对于范围，建议使用GSM屏蔽。

如何使用wifi将arduino发送传感器数据到服务器？
