6 Contaminants build-up in the measurement chamber or optical
7 elements deterioration leads to sensor drift.
9 One can compensate for sensor drift by using automatic self
10 calibration procedure (asc).
12 Writing 1 or 0 to this attribute will respectively activate or
15 Upon reading current asc status is returned.

22 Contaminants build-up in the measurement chamber or optical
23 elements deterioration leads to sensor drift.
25 One can compensate for sensor drift by using forced
26 recalibration (frc). This is useful in case there's known
27 co2 reference available nearby the sensor.
29 Picking value from the range [400 1 2000] and writing it to the
32 Upon reading current frc value is returned. Note that after
33 power cycling default value (i.e 400) is returned even though
34 internally sensor had recalibrated itself.
