Temperature and Humidity Sensor with Arduino

                                         
Parts Used
1.

                                   DHT11 sensor – Temperature and Humidity module

2.

                                           Jumper Wires male to male – 65pcs

3. 
                                                                         UNO R3


CODE
#include <DHT.h>
#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()
