    Temperature Accuracy BME688

    Hi all,

    I did my first measurements with the BME 688 Dev-Kit and noticed that the measured temperature is quite high. Instead of getting around 22°C (room temperature) the sensors measured between 42-45°C.

    I can imagine it is because of the heating gas sensors. Unfortunatelly there is no heater profile with room temperatures. Is it possible to customize the heating profiles or may turn it off completely?

    Best,

    Jac

    Hi JacRob, 

     

    That's correct. What is purpose for BME688? Do you want to use gas scanning feature in BME688? 

    If yes, BME688 is not appropriate for room temperature due to heating profile. 

    Thank you.

    Hi Minhwan,

    first of all, thank you for your quick response. 

    Currently we use an extra sensor to measure temperature and humidity. Would have been nice if we could also use that data to get rid of the other sensors. Additionally that seems to influence the humidity measurement. Towards your statement, for which temperature areas can I trust the measured temperature? Is there any approximation? 

    Yes, our main purpose is to use the gas sensor in future but I was wondering if the sensor is working correctly or something is incorrect.

    Another short question, the Andriot app seems to be a demo version. Is the full version not released yet? Or do I can get it from somewhere else?

    Best regards,

    Jacques

    Hi Jacques, 

     

    As long as you are using gas scanning mode, we don't recommend to use temp and humidity as you understand. 

    In terms of Android app, I don't think we are going to release whole source code, but only app level. 

    We might upgrade official version, but not plan it right now. 

    Thank you.
