Sample Code: 

#define dht_apin A0 // Analog Pin sensor is connected to dht DHT; 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
