 * @brief TempHum16 Click example
 *
 * # Description
 * This library contains API for the Temp&Hum 16 Click driver.
 * This demo application shows an example of 
 * humidity and temperature measurement.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of SPI or I2C module and log UART.
 * After driver initialization and default settings, 
 * the app display retrieves the sensor parameters 
 * such as temperature and humidity.
 *
 * ## Application Task
 * This is an example that shows the use of a Temp&Hum 16 Click board™.
 * Logs humidity [ % ] and temperature [ degree Celsius ] data.
 * Results are being sent to the Usart Terminal where you can track their changes.
