Is it possible to detect only H2S gas with BME688?

[kyusanglee]

hello
We are planning to use BME688 for smart diapers.
Because of that, I have three questions.

1. I would like to know if only H2S gas can be detected in BME688 Developmet Desktop. (If possible, please share how to use it.)

2. When using the AI function in the BME688 Development Kit, can H2S gas and general air be learned?
The key point of use is the distinction between stool and urine.

3. Is there a manual for turning off the remaining gases in BME688, leaving only the H2S gas?

Hi kyusanglee,

Thanks for your inquiry.
1.Developmet Desktop does not support gas detection. The official hardware and software that support gas detection are the BME688 dev kit and BME AI-Studio mobile app, you can see it from https://www.bosch-sensortec.com/media/boschsensortec/downloads/product_flyer/bst-bme688-fl001.pdf
2.Yes;
3.BME688 does not have such an option.
