Code:

Arduino
#include<dht.h>
dht DHT;
//  if  you require to change the pin number, Edit the pin with your arduino pin.
#define DHT11_PIN 3 
void setup() {
Serial.begin(9600); 
Serial.println("welcome to TechPonder Humidity and temperature Detector");    }
void loop() {   // READ DATA 
int chk = DHT.read11(DHT11_PIN); 
Serial.println(" Humidity " ); 
Serial.println(DHT.humidity, 1); 
Serial.println(" Temparature "); 
Serial.println(DHT.temperature, 1);
delay(2000); 
}
