I am a student of M.Sc. product design. I am currently working on my Master's thesis where I am designing a device to differentiate smells for users suffering from smell impairment. I found that the BME688 sensor can detect and differentiate the different smells based of pretrained algorithms. I currently have the BME688 Developer Kit with 8 sensors (https://buyzero.de/products/bosch-bme688-gas-sensor-developer-kit?variant=37884583215284) and the BME688 Breakout Board for Raspberry Pi from Pi3G (https://pi3g.com/products/bme688-breakout-board/). I do not possess sound knowledge of raspberry pi and other electronics since I am from a mechanical engineering background. I have been able to record measurements for different smells such as coffee, tea, garlic, cinnamon and others using the Developer Kit referring to the Bosch video (https://www.youtube.com/watch?v=4vdliMRtxBY). I have also trained the algorithm and exported the config file from Bosch AI Studio. I would like to use this config file with my BME688 breakout board and raspberry pi and detect the different smells as mentioned above. I would like you to help me out by telling me where to get started and how to go about it since I am new to this field. Also I would be greatful if someone could share any files related to procedures that need to be followed to get the desired output.
Thanks in advance.
