I am working on an environmental monitoring system for my house as a personal project, and I am planning to have a VOC sensor as part of my configuration. My understanding is that MOX sensors like the BME688 are not normally able to estimate the concentrations of individual VOCs, but only a total measurement of all VOCs in the air (the TVOC).
However, from what I can tell, the BME688 is capable of more levels of discrimination than most MOX sensors due to the adjustable heating and the AI subsystem.
Is it possible to use this to get a rough approximation of the levels of different types of VOCs in the atmosphere using the BME688?

Currently the algorithm haven't support the detection of VOCs level.
