BME688 - CO2 precision

[NBG]

Hi,

Im using a BME688 with BSEC-2.0.6.1 software. Everything seems to run okey and the values are more or less precise, except the C02 value, wich is 200-500ppm above the real value. How can I fix it?

Thanks.

Hi NBG,

BSEC output co2 equivalent estimate [ppm].

Hi,

for example, the co2 output of BSEC is 1000ppm, but the real value is 500ppm. There is a lot of difference. I would like to know how can I calibrate it.

Thanks

Hi NBG,

BSEC outputs an estimated CO2 value, and there is no algorithm to calibrate it at present.
