 * 
 * # Description
 * This application detects any motion around it and shows message
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes Driver enable's the motion detection.
 * 
 * ## Application Task  
 * Detect the motion and send a notification to the UART.
