/*Here's a breakdown of what this code does:

Import the DHT library.
Define the pin to which the DHT sensor is connected (DHTPIN) and the type of the sensor (DHTTYPE). Change DHTTYPE to DHT12 if you're using a DHT12 sensor.
Initialize the DHT sensor object.
In the setup() function, start serial communication and print a message to indicate that the DHT sensor is being tested.
In the loop() function, wait for 2 seconds.
Read humidity and temperature values from the sensor.
Check if the readings are valid.
If valid, print the humidity and temperature values to the Serial Monitor.
Make sure you have installed the DHT library in your Arduino IDE. You can do this by going to Sketch > Include Library > Manage Libraries, then search for "DHT" and install the library developed by Adafruit.*/
