* 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.
