BSTRobin, Thanks for responding! I'm aware of the recomended temperature and duration settings, but I don't know why they are what they are. I've already experimentally determined that I can't just randomly choose a value within the recomended ranges - big difference between 200C and 400C. Why did changing the temperature change the response? I've found a few university papers that discuss MOX sensor experiments, but my research is duplicating the labor that's already been spent by other users. I'd rather not have to repeat the journey Bosch took to understand and characterize the BME688. It would be a magic moment in customer service for Bosch to share their data with their customers - who also happen to be engineers. Is there a whitepaper, journal article, etc.? My question is general in nature, so I'll address the specifics of my application in another post.
