Inconsistent values of bme688 raw_gas

[yang2024]

I tested three sensors in the same environment, and two of them had values that were relatively close, while the other had values that were significantly different. Is this normal?

num	raw_gas
1	49600
2	72112
3	43800

Hi yang2024,

In the same environment, the gas resistance values between BME688 sensors cann't be the same, as there is a deviation of+/-15% between sensors.

From the three resistance values you tested, they are within the normal range specified in the data sheet.
