    how to calculate CO2 equivalent and VOC using PIC32MX370/470 MCU?

    Hello,

    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.

     

    Best regards

    Ankur

    If you need the CO2 equivalent and VOC (IAQ index) output,  you must use our BSEC lib. 

    The BME680 only output gas register value.  Without lib, we can't compensate it and output your desired value.

    If your MCU is not included in the support list of our BSEC pre compiled lib,  you can leave your compiler details here. 

    Then we can try to build a special BSEC lib version for you.

    Yes, we will try to build a lib for you.

    Did you use any special compiler parameters in your project?

    Hello,

    Kindly suggest which type of special compiler parameter you are asking for.

    Thank you
