nodemcu+DHT11上传数据到自己的远程服务器

我是靠谱客的博主潇洒诺言，这篇文章主要介绍nodemcu+DHT11上传数据到自己的远程服务器，现在分享给大家，希望可以做个参考。

前言：近期做了一个物联网项目，我是做硬件部分的，任务是把DHT11测得的温湿度数据上传到远程服务器，因为以前没有接触过这些，互联网知识什么也不懂，前期做的很艰难，后来也是翻遍csdn,找到了些别人的资料，才把这个项目做完。发这篇博客的目的是怕代码丢了，以免以后忘记，有什么错误之处。还请批评指正

所需物料：家里的路由器、一台能连WIFI的电脑、一个nodemcu开发板、一根安卓数据线、两个DHT11模块、杜邦线若干

代码如下，我怕解释不好，就不做解释了

复制代码

const char *ssid     = "Tenda_1C50E8";//
const char *password = "12345678";//
const char *host = "115.29.142.200";//服务器IP
const int httpPort =89;//端口号
String line ="";
int m=0; 
int i=0;

float wendu1,wendu2,shidu1,shidu2;

void setup() {
  Serial.begin(115200);
  delay(10);
  pinMode(relay1,OUTPUT);
  // We start by connecting to a WiFi network
 
  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);
  
  WiFi.begin(ssid, password);
  
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
 
  Serial.println("");
  Serial.println("WiFi connected");  
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
  while (!client.connect(host, httpPort)) {
    Serial.println("connection failed");
    //return;
    delay(500);
  }
  Serial.print("connecting to ");
  Serial.println(host);
 // delay(1000);

}

               client.println();
           Serial.println("S001发送成功======");
