Temperature and Humidity monitoring with Arduino Uno R3

#include <DHT.h>; // Import the library of the DHT sensor

#define SENSORPIN 12     // The sensor pin to which we are connecting in the arduino = Pin no. 12
#define SENSORTYPE DHT22   // The DHT sensor model we are using = DHT22
DHT dht(SENSORPIN, SENSORTYPE); // Define the model and pin number of the dht sensor

float humidity;    //Variable for storing humidity
float temperature; //Variable for storing temperature

void setup()
{
  Serial.begin(9600); 
  Serial.println("Starting to measure the humidity and temperature...");
  dht.begin();  //Starting the DHT22 sensor
}

void loop()
{
    delay(2000); //delay of 2 seconds
   //Read data from the sensor and store it to variables humidity and temperature
    humidity = dht.readHumidity();
    temperature = dht.readTemperature();
   //Print the values of humidity and temperature in the serial monitor
    Serial.print("Humidity: ");
    Serial.println(humidity);
    Serial.print("Temperature: ");
    Serial.print(temperature);
    Serial.println(" Celsius");
