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);
}
Itulah Pembahasan materi script Dht 11+ relay, jika ada kesalahan penulisan Mohon maaf, karena kesempurnaan hanyalah milik Tuhan Yang Maha Esa. selamat mencoba, semoga bermanfaat.
