This extension adds some new units and conversions to WeeWX. They are neccassary for the observations provided by airQ device.
Note: Some observation types can be expressed as concentration as well as fraction. The unit group of the pre-defined observation types of WeeWX does not always correspond to the unit group provided by the airQ device. In those cases you will find the observation types both at concentration section and fraction section.
