BME688 Compensated Temperature

[HUYNHIEN]

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?

Hi BSTRobin, 

Thank for your feedback.

I'm using [Bosch-BSEC2-Library-master] library for my test.
