I'm developing a real-time coffee roasting gas analyzer that requires datapoints roughly every second over a span of about 6-10 minutes. Looking for any guidance for sensor temperature and duration settings for the BME688 that are optimal for high update rates.
Bosch's coffee test example is interesting, but that took eight sensors, 30 minutes, and a neural network - yikes. Those same gases in a real-time roasting scenario will change by orders of magnitude within the space of about one minute, and the timing of that change is crucial to guiding the roasting process. Both data collection and analysis have to complete in real time. Whatever settings are optimal for the sensor in a sealed jar for half an hour may not be entirely suitable.
So, what is the guidance on temperature and duration for sensing coffee at a 1-second update rate?
