Thanks for your answer. I need to measure Co2 up to a maximum of 30% (V/V) according to the image below. Is it possible with Bme680 or Bme688? I do not see the maximum eCo2 output value (Bsec) in the table. Can you suggest any sensor with I2C output that meets this requirement? Thank you. yours
If your application requires precise measurement of CO2 concentration, BME688 will not be able to achieve such measurements. BME688 does not directly measure CO2, and the CO2 output from BSEC is calculated based on VOCs equivalence.
