BSEC BME688: BSEC_OUTPUT_GAS_PERCENTAGE

[matteo]

Hi, i want to ask if someone can clarify the meaning of the BSEC output BSEC_OUTPUT_GAS_PERCENTAGE and how it can be used as a parameter in air quality monitorning application. Thanks.

Hi Matteo, 

BSEC_OUTPUT_GAS_PERCENTAGE is the percentage of filtered gas value. 

For Air quality monitoring application, I strongly recommend to use BSEC_OUTPUT_IAQ or BSEC_OUTPUT_STATIC_IAQ. 

Because Bosch Indoor air quality as known as IAQ is based on gas value, so you can provide your or your customer's indoor information to them. 

It's hard to say about IAQ based on gas percentage. 

Thank you.
