 * \brief DHT22 2 Click example
 * 
 * # Description
 * This example demonstrates the use of DHT22 2 click board by reading
 * the temperature and humidity data.
 * 
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Reads the temperature (degrees C) and the relative humidity (%RH) data and 
 * displays the results on the USB UART approximately once per second.
