Please take care, arduino A0 pin represent the analog input configured on #define pin
Please make sure arduino A0 pin represents the analog input configured on #define pin
This example code is in the public domain.

// 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
// In this routine the sensor will measure the resistance of the sensor supposedly before being pre-heated
// and on clean air (Calibration conditions), setting up R0 value.
// We recomend executing this routine only on setup in laboratory conditions.
// This routine does not need to be executed on each restart, you can load your R0 value from eeprom.
