Hello,
I am new to the BME688 sensor and I need to help to decouple the humidity and gas measurement. When I espose the sensor to solvents (Acetone, IPA or ethanol) the humidity changes in the order of 3-5% that follow the gas concentration, especially with acetone. When I expose the sensor to water I get significant gas resistance variation. I attach the raw data extracted from the BSEC2 library for Arduino IDE 2.0.3.
How can I know if the resistance measurement is due to gas sensing and not variations in humidity and vice versa?
Thank you!

Hi Christoforos,
For temperature and humidity value, they has been compensated in BME68X sensor API code.
For BSEC gas output, it depends on temperature and humidity values for compensation.
