The sensors are not independent.

Gas sensing is really tricky. Metal oxide gas sensors respond nonlinearly to all three of gas, temperature, and humidity. Plus they drift. AI can help with the nonlinear response. Drift hasn't been solved yet, as far as I know.

Understood,the point was if the sensors are identical, they don't give any more information, some independence is needed.
