I using the BME688 sensor, and would like to understand the collected data for basic understanding. The used operating config can be found below.
Based on my understanding, every heating profile consists 10 sampling on a pre-defined time (same in each cycle). The maximum selectable heating profile is 4 which means that in any case at least two sensor would operating at the same time, i.e., collecting data labeled with the same timestamp. Furthermore, the selected heating profiles have the following duration; 18.34s, 10.78s, 24.64s, 26.88s. This would mean that two sensor (10.78s) should collect approx 2.3, and two (18.34s) approx 1.4 times of data than the other four (24.64s and 26.88s).
But I experienced the following:
Could you please help me understanding why
Solved! Go to Solution.
The BME688 Gas Sensor (How gas sensing gets intelligent with BME688 and BME AI-Studio (long version) - YouTube), ordering code: 0330.EKB.016
What we need to understand here is about the board layout and the sensor configuration
Default can be something like this when we have the mentioned profiles (18.34 sec - HP 301,10.78 sec - HP 354, 24.64 sec - HP 411
26.88 sec - HP 501)
This would mean Sensors 1,2 belong to HP354 and others as shown in the board layout
Here the duty cycling is RDC 1-0 (Continuous) , we are not sure what the user has configured at your end.
It would be better if the you can share config file generated for this data collection.
