    Issues with (BME688) AI Suite results

    Yo! 

    I'm using the BME688 and have 2 test devices. We are trying to detect cigarette smoke with the sensor and have been doing testing in a large room with smoking for 5 minutes and then letting the air return to normal. 

    We have the sensors algorithm saying that the smoke from the cigarettes matches anything from apples and oranges to various other things.

    This testing is for commercial use and we have already order 7000 BME688s for testing and would very much like some more support but there seems to be no more infomation on proper testing and various applications or even how to use the AI Suite in a more indepth fashion.

    Is there anyone we can talk to and what about the advanced user settings?

    Hello Russell-SIBI,

    With your description, could we know more information for your test device and software?

    We filled a room with 5 minutes of smoke and measured that multiple times. The algorithm we got had a 98% accuracy rating. We then tested that alogorithm vs fruit and coffee "Condensed" ie inside a sealed container. 

    The BME688 said that all of them were the same air composition. 

    What would cause this and how can we get more accurate results?

    Hello Russell-SIBI,

    You could refer the application note and use BME AI-Studio Software that enables sensor configuration, data analysis & labelling, training and optimization of application-specific solutions.
