We tried to use all 4 classes in the BME AI-Studio: Class A: Air Class B: Coffee Class C: Tea Class D : Flower Then in our application with BSEC Library we got for Air: BSEC_OUTPUT_GAS_ESTIMATE_1=0.00 BSEC_OUTPUT_GAS_ESTIMATE_2=0.99 BSEC_OUTPUT_GAS_ESTIMATE_3=0.00 BSEC_OUTPUT_GAS_ESTIMATE_4=0.00 for Coffee the same: BSEC_OUTPUT_GAS_ESTIMATE_1=0.00 BSEC_OUTPUT_GAS_ESTIMATE_2=0.99 BSEC_OUTPUT_GAS_ESTIMATE_3=0.00 BSEC_OUTPUT_GAS_ESTIMATE_4=0.00 It looks like BSEC_OUTPUT_GAS_ESTIMATE_1 doesn't change at all. If we remove classes C and D from the algorithm, we get for Air: BSEC_OUTPUT_GAS_ESTIMATE_1=0.99 BSEC_OUTPUT_GAS_ESTIMATE_2=0.00 and for Coffee: BSEC_OUTPUT_GAS_ESTIMATE_1=0.00 BSEC_OUTPUT_GAS_ESTIMATE_2=0.99 this is correct.

Hello, I did everything in accordance with the manual "Getting started"(Example: Coffee vs. Normal Air). I used all the default settings. I have successfully exported the BSEC Configuration File and included it in my application. My coffee is recognized correctly(BSEC_OUTPUT_GAS_ESTIMATE_1=0.99). But many other smells (e.g. tea, perfume, flowers, etc.) are also identified as this coffee(BSEC_OUTPUT_GAS_ESTIMATE_1=0.98..0.99). BME AI Studio: 1.6.0 BME68x: 4.4.6 BSEC: 2.0.6.1 What am I doing wrong? Thanks, Dan ... View more
