I created 2 AI models, one for coffee similar to the youtube video and one for foul vegetables. Both algorithms produce probabilities > 95%. I checked the configuration file output from AI Studio with 3 different applications: Arduino ESP32 (exact the ino example in BSEC 2.0), ESP32 in eclipse development environment and on a STM32 nucleo platform, all linked with libalgobsec.a (depending of the MCU used). In every test I get the result Gas Estimate 1 (normal air -> 1.0). Whatever I do I never get any probability > 0.0 in Gas Estimate 2, even if probe within the Coffee glas or in the fouled vegetable container. Any experience with BME688?
For sampling I used BME 688 dev kit board (8 sensors) on Adafruit HUZZAH32
Recommend you to put the trained config string into SD card of same EKB board(which is used to collect the data) and have a test on the target gas. Could have a try and give feedback?
thanks for reply. I got a .config file from the AI. What happens, if I put it back to the SD Card? Does the ESP32 generate a log file instead of sampling new data? Any documentation for the steps you suggest?
After you got config file, you could import it to BSEC example and run it. You could download BSEC package from here:
There are deriver code, example code, integration guide under BSEC package. You could refer integration guide to do step by step operation.
this ist exact the software I use and I have problems with! Whatever I measure coffee, foul vegetables, every time class normal air is returned
