 * 
 * # Description
 * This demo shows basic TempHum13 Click functionality - temperature
 * and humidity measurement. 
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialize device.
 * 
 * ## Application Task  
 * Measure temperature and humidity values on every 0,5 seconds,
 * and log them to UART Terminal if they are valid.
