 * @file main.c
 * @brief TempHum19 Click example
 *
 * # Description
 * This example demonstrates the use of Temp & Hum 19 click board by reading
 * the temperature and humidity data.
 * 
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Reads the temperature (Celsius) and humidity (Percents) data and displays the
 * results on the USB UART approximately once per second.
