 * 
 * # Description
 * This application enables usage of IR sensor for presence detection.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Driver initialization.
 * 
 * ## Application Task  
 * Fetches IR and temperature sensor data and prints them on terminal.
