void setup(){

 

  Serial.begin(9600);

  delay(500);//Delay to let system boot

  Serial.println("DHT11 Humidity & temperature Sensor\n\n");

  delay(1000);//Wait before accessing Sensor

 

}//end "setup()"

 

void loop(){

  //Start of Program 

 

    DHT.read11(dht_apin);

    

    Serial.print("Current humidity = ");

    Serial.print(DHT.humidity);

    Serial.print("%  ");

    Serial.print("temperature = ");

    Serial.print(DHT.temperature); 

    Serial.println("C  ");

    

    delay(5000);//Wait 5 seconds before accessing sensor again.

 

  //Fastest should be once every two seconds.

 

}// end loop()
