Tutorial: Monitor temperature and humidity using DHT11

This is an Arduino sketch that monitor temperature in Celsius degrees and humidity
in percentage by using the DHT11 sensor with Arduino

Connections from the Arduino to the DHT11:
• Arduino GND pin → DHT11 GND pin (- pin)
• Arduino 5V pin → DHT11 VCC pin (+ pin)
• Arduino pin 3 → DHT11 out pin

*/

//include the DHT sensor Library
#include < DHT.h > 

//Define Parameters to DHT function, 3 Refers to digital pin 3 in arduino which you can change with any other digital pin, DHT11 is the sensor type.
DHT dht(3, DHT11);

//define two variables for Temperature and Humidity.
float Temperature, Humidity;

// Commands inside void setup run once.
void setup()
{
//Initialize the DHT sensor with the begin() method.
dht.begin();

//Start the serial monitor at 9600 baud rate (9600 bits per second)
Serial.begin(9600);
}

//Commands inside void loop run forever
void loop()
{
//wait for 1 sec to get a stable reading from the sensor
delay(1000);

//Read the Temperature value from the sensor
//You can use Temperature = dht.readTemperature(True); to print the temperature value in Fahrenheit.
Temperature = dht.readTemperature();

//Read the Humidity value from the sensor
Humidity = dht.readHumidity();

//print "The Temperature = " to the serial monitor
Serial.print("The Temperature = ");

//print temperature value at the same line
Serial.print(Temperature);

//print " Celsius" to the serial monitor at the same line
Serial.print(" Celsius");

//print "   The Humidity = " to the serial monitor at the same line
Serial.print("   The Humidity = ");

//print The Humidity value to the serial monitor at the same line
Serial.print(Humidity);

//print "%" sign to the serial monitor then add new line
Serial.println("%");
