getSensorVariant не работает.

getSensorVariant не работает, всегда обнаружен SCD40.

SensirionI2cScd4x.cpp line 174.

uint16_t variant = (uint16_t)(rawSensorVariant & 4);

Надо проверять bit 12 (0x1000), а проверяется bit2 (& 4, 0x0004)

variant всегда равен 0.

Далее проверку тоже надо изменить.

Agree with @SoftFelix72. But not everyone may understand Russian language. So, maybe this helps:

Line 174 should be changed to:

uint16_t variant = (uint16_t)((rawSensorVariant & 0x1000)>>12);

Hi. Yes, now it's correct and it will work. I didn't shift by 12, but compared directly with 0x0000 and 0x1000. :) So your code is more beautiful. In any case, the library needs to be officially fixed.
