 * @brief TempHum20 Click example
 *
 * # Description
 * This example demonstrates the use of Temp & Hum 20 click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger and performs the click default configuration 
 * which resets the device and sets it to normal operating mode.
 *
 * ## Application Task
 * When the new data is ready, this function reads the temperature and humidity data 
 * and displays the results on the USB UART.
