// Explanation:
// In this routine the sensor will measure the resistance of the sensor supposing before was pre-heated
// and now is on clean air (Calibration conditions), and it will setup R0 value.
// We recomend execute this routine only on setup or on the laboratory and save on the eeprom of your arduino
// This routine not need to execute to every restart, you can load your R0 if you know the value
// Acknowledgements: https://jayconsystems.com/blog/understanding-a-gas-sensor
