 * \brief Airquality5 Click example
 * 
 * # Description
 * This application can detect gas pollution for a number of different gases.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes device and configuration chip.
 * 
 * ## Application Task  
 * Reads the values of CO, NH3 and NO2 sensor and logs data on USBUART every 500ms.
