Arduino Uno с ESP8266-01 с AT

Вот схема, которой я следовал:

Вот и ссылка: https://www.circuito.io/app?components=10167 ,11021,12083,13678,13959

#include "DHT.h"

#define DHTTYPE DHT11   // Тип DHT - DHT 11 (AM2302)
#define TRIGGER_PIN 4

NewPing sonar(TRIGGER_PIN,ECHO_PIN,MAX_DISTANCE);

float hum;
float temp;   

DHT dht(DHTPIN, DHTTYPE); 

void setup()
{
  Serial.begin (9600);
  dht.begin();

  pinMode(TRIGGER_PIN, OUTPUT);
  pinMode(ECHO_PIN, INPUT);

  sendData("AT+RST\r\n",2000,DEBUG);            
  sendData("AT+CWMODE=2\r\n",1000,DEBUG);

  sendData("AT+CIPSERVER=1,80\r\n",1000,DEBUG); 
}

void loop() 
{
  delay(2000);  // Задержка, чтобы датчик DHT-11 мог стабилизироваться

  hum = dht.readHumidity();  // Получить значение влажности
  temp= dht.readTemperature();  // Получить значение температуры

  digitalWrite(TRIGGER_PIN, LOW);
  delayMicroseconds(2);
  digitalWrite(TRIGGER_PIN, HIGH);
  delayMicroseconds(10);
  digitalWrite(TRIGGER_PIN, LOW);

  long duration,distance;
  duration = pulseIn(ECHO_PIN,HIGH);

  distance = duration/58.2;

  Serial.print("Humid: ");
  Serial.print(hum);
  Serial.print(" %, Temp: ");
  Serial.print(temp);
  Serial.print(" C, ");
  Serial.print("Distance: ");
  Serial.print(distance);
  Serial.println(" cm");
  delay(50); 

  if(esp8266.available())
  is sending a message 
  {    
    if(esp8266.find("+IPD,"))
    {
      delay(1000);
      int connectionId = esp8266.read()-48;
      /* We are subtracting 48 from the 
         output because the read() function returns 
         the ASCII decimal value and the 
         first decimal number which is 0 starts at 48 */
      String webpage = "<h1>IOT Garbage Monitoring System</h1>";
      webpage += "<p><h2>";   
      if (distance<5)
      {
        webpage+= " Trash can is Full";
      }
      else{
        webpage+= " Trash can is Empty";
      }
      webpage += "</h2></p></body>";  
      String cipSend = "AT+CIPSEND=";
      cipSend += connectionId;
      cipSend += ",";
      cipSend +=webpage.length();
      cipSend +="\r\n";

      sendData(cipSend,1000,DEBUG);
      sendData(webpage,1000,DEBUG);    
      String closeCommand = "AT+CIPCLOSE="; 
      closeCommand+=connectionId; 
      closeCommand+="\r\n";
      sendData(closeCommand,3000,DEBUG);
    }
  } 
}

String sendData(String command, const int timeout, boolean debug)
{
  String response = "";   
  esp8266.print(command); 
  long int time = millis();
  while( (time+timeout) > millis())
  {
    while(esp8266.available())
    {
      char c = esp8266.read(); 
      response+=c;
    }  
  }
  if(debug)
  {
    Serial.print(response);
  }
  return response;
}

Я пытаюсь решить эту проблему уже почти неделю.
