DHTxx for Arduino Code

I needed to check the exact temperature of a aircon room to display my fact that an ac room is not what it says on the remote. so I decided to make this.

you will need x1 breadboard (optional)

x1 set of wires

x1 dhtxx

x1 Arduino uno

so connect (left to right)

Pin 1 to 5v

pin 2 to digital pin 7

pin 3 (just leave it)

Pin 4 to GND

it will DISPLAY in C, F, K and humidity

Here the code

Thanks

//Libraries
#include <DHT.h>;
//#include<iostream>:
//Constants
#define DHTPIN 7     // what pin we're connected to
#define DHTTYPE DHT22   // DHT 22  (AM2302)
DHT dht(DHTPIN, DHTTYPE); //// Initialize DHT sensor for normal 16mhz Arduino
//Variables
int chk;
float hum;  //Stores humidity value
float temp; //Stores temperature value
float faran;
float kel;
void setup()
{
 Serial.begin(9600);
 dht.begin();
}
void loop()
{
   delay(2000);
   //Read data and store it to variables hum and temp
   hum = dht.readHumidity();
   temp= dht.readTemperature();
   //Print temp and humidity values to serial monitor
   Serial.print("Humidity : ");
   Serial.print(hum);
   Serial.println(" %");
   Serial.print("Temp     :");
   Serial.print(temp);
   Serial.println(" Celsius");
   faran = (temp * 9.0) / 5.0 + 32;
   Serial.print("Faranheit: ");
   Serial.print(faran);
   Serial.println(" F");
   kel = temp + 273.15;
   Serial.print("Kelvin: ");
   Serial.print(kel);
   Serial.println(" K");
   Serial.println("");
   Serial.println("");
   delay(5000); //Delay 5 sec
