 * 
 * # Description
 * This application measurement temperature and humidity data.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes device and logger module and sets default configuration for measurements.
 * 
 * ## Application Task  
 * Calculates and Logs temperature and relative humidity
