 * # Description
 * The demo application gets Alcohol data and logs data to USBUART.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes device configuration.
 *  
 * ## Application Task  
 * Gets Alcohol (C2H5OH) data and logs data to USBUART every 500ms.
