The BME680 alone can only output raw temperature, absolute pressure, relative humidity, and gas resistance.
How can I calculate CO2 equivalent and VOC without the library?
I did not find any formula neither in the BME680 datasheet nor in the API.
I am using PIC32MX370/470 MCU.
Solved! Go to Solution.
The following two output virtual sensor is the sensor you are requested.
BSEC_OUTPUT_CO2_EQUIVALENT = 3, /*!< co2 equivalent estimate [ppm] */
BSEC_OUTPUT_BREATH_VOC_EQUIVALENT = 4, /*!< breath VOC concentration estimate [ppm] */
They are part of the lib which i released to you.
In the example code bsec_integration.c in the release package, you can find the function bme680_bsec_update_subscription. you can add these two output sensor into the enable senser list. then you should able to get those two output from lib.
