Assalamualaikum Wr. Wb.

        Hallo, Kembali lagi di Blog saya Raul Arjuna, Jadi pada pembahasan Kali ini Saya akan memberikan lampiran script Project dht 11+Relay menggunakan NodeMCU pada Aplikasi ThingSpeak. Jadi Langsung saja kita ke Pembahasannya

Berikut Scriptnya :

#include "DHT.h"

#include <ESP8266WiFi.h>

#define relay 0

#define DHTPIN 2

#define DHTTYPE DHT11

DHT dht(DHTPIN, DHTTYPE);

WiFiClient client;

String apiKey = "TWR59QEXTCKTTOFY";

const char* ssid = "WuLn";

const char* pass = "12345678";

const char* server = "api.thingspeak.com";

void setup(){

  Serial.begin(9600);

  pinMode (relay,OUTPUT);

  digitalWrite (relay,LOW);

  delay(10);

  dht.begin();

Serial.println("Connecting to ");

  Serial.println(ssid);

WiFi.begin(ssid, pass);

  while (WiFi.status() != WL_CONNECTED){

    delay(500);

    Serial.println(".");

    }

  Serial.println("");

  Serial.println("WiFi connected");

}

void loop()

{ 

  float h = dht.readHumidity();

  float t = dht.readTemperature();

  if (isnan(h)||isnan(t)){

      Serial.println("Failed to raed from DHT sensor!");

      return;

    }

if(client.connect(server, 80)){

    String postStr= apiKey;

    postStr += "&field1=";

    postStr += String(t);

    postStr += "&field2=";

    postStr += String(h);

    postStr += "\r\n\r\n";

client.print("POST /update HTTP/1.1\n");

    client.print("Host: api.thingspeak.com\n");

    client.print("Connection: close\n");

    client.print("X-THINGSPEAKAPIKEY: "+apiKey+"\n");

    client.print("Content-Type: application/x-www-form-urlencoded\n");

    client.print("Content-Length: ");

    client.print(postStr.length());

    client.print("\n\n");

    client.print(postStr);

Serial.print("Temperature: ");

    Serial.print(t);

    Serial.print(" degrees Celcius, Humidity: ");

    Serial.print(h);

    Serial.print("%. Send to Thingspeak.");

  }

  if (t < 35 ){

    Serial.println("NYALA");

    digitalWrite(relay, HIGH);

    delay(500); 

  if ( t > 35 )

    Serial.println ("MATI");

    digitalWrite (relay,LOW);

    delay(500);

  }

  else 

  {

    Serial.println("MATI");

    digitalWrite(relay, LOW);

    delay(500);  

  }

  client.stop();

  Serial.println("Waiting...");

  delay(1000);

}
