In this post in the knowledge-base the value "sensor compensated gas resistance" is specified and described as follows:
"The sensor compensated gas resistance provides the gas resistance compensated by temperature and humidity influences"
However looking at the code(bsec_datatypes.h, line 298) as well as the BSEC integration guide(page 45, top) "BSEC_OUTPUT_COMPENSATED_GAS" is described as " reserved internal debug output" (page 45, top).
Reading the value from the BSEC library gives an odd value (6.34 Ohm when raw_gas is 369129.03 Ohm), and its accuracy is always 0.
I would very much like the compensated value, and hope someone can help me get it.
Thanks in advance.

Thank-you for you feedback, there seems to be indeed some mistakes in the documentation that have now been reported.
Regarding the outputs:

Good to know. Then either the library should be updated to return the value in Ohm, or the unit should be changed in the output explaination.
Calculating 10^comp_gas_value gives a value much higher than the un-compensated.
raw_gas: 224,186 Ohm
compensated_gas: 10^(6.167286)=1,469,893.9 Ohm
Can anyone with a bit more experience with compensated gas resistance values tell me if that seems right?

Alright. Thanks for your help!
