 *  RE-Mote external IAQ test application
 *  Example of iAQ-Core implementation and simple operation reading the value
 *  of CO2, TVOC sensor and Status. The test checks for a each 5 minutes in
 *  order to get the first true measurement as datasheet recomendation
 *  (standard result of 0x82 is obtained in first time).
 *  Then, once initialized, periodically each 5 seconds reads
 *  the values of the IAQ sensor and shows in the screen, toggling the LED
 *  red if CO2 was not initialized and LED green if the reading was succeed.
