Under live test of BME688, why do the 4 sensors give 4 prediciton instead of one?

In addition, only Sensor 1-4 works. Sensor 5-8 never give any prediction. Anyone knows why?

Hi rainyboy999,

BME AI-Studio only supports a maximum of 4 classifications.

Thank you. But I think you did not understand my question. For example, I only have two Classes (Class A and B) to differentiate. But 4 sensors (U1-U4) will give separate predictions and they could be different. For example, U1 and U2 may predict as Class A. But U3 and U4 predict as Class B. So which one should I trust if it is a blind test? The accuracy of the algo is based on which sensor? Do the sensors vote?

Hi rainyboy999,

Currently the app only support U1~U4, haven't supported U5~U8.
In theory, if the test environment is the same, the output from U1~U4 should be close.
