    BME688 Compensated Temperature

    Hi everyone,

    I want to measure temperature and recognise gas simultaneously with "basic_config_state.ino"in Bosch-BSEC2-Library-master. I have a problem here with the temperature value.It has big difference between the compensated temperature's value and real temperature which be measured by a thermometer.

    (When I used "basic.ino" program which does not recognise gas, the temperature is almost the same with the thermometer's value.)

    Could you please tell me how I can get the compensated temperature's value correctly when the sensor can recognise the gas simultaneously ?

    Many thanks.

    Hi HUYNHIEN,

    Do you have a log of the temperature before compensation, the temperature after compensation and the actual temperature?

    Hi BSTRobin,

    I attached the serial monitor capture when I ran the "basic_config_state.ino" program, and the actual temperature .
    I'm looking forward hearing from you soon.

    Many thanks.

    Hi HUYNHIEN,

    Thank for your feedback.

    From your log, you can see that the output temperature of "basic_config_state.ino" is different from the ambient temperature.
    By the way, what's sensor API you used?
