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

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