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!
