BME 680 and BME 280 Not Reading Constant Humidity

[Veronica716]

Hi Jet,

I don't think I am using BME280 API. I am using a library in my arduino code called Adafruit_BME280.h

Would the BME280 API account for this problem I am having?

Hi Sir:

   I will forward your mind to our internal experts. If any update, I will keep you informed.

Hi Sir：

  Talked with internal experts, we didn't think you were wrong in anything. But we have still thought the relative humidity and the absolute humidity with the temperature change is not constant under your test condition, you need offer the reference to confirm your expection.

  More information and support you should contact your local FAE to get.

Hi Sir:

    Do you have any update? If possible,  please offer the raw data and reference data to us, include temperature/relatvie humdity/absolute humidity/ absolute humidity of reference device.

   Thank you.

Hi Jet,

I undertsand that you all don't believe the water content in my jar is constant. Could you explain to me why you think this is the case? Like I mentioned before, I have done a lot of research to find a possible way that the water content could not be constant. It seems that you have the answer to this. Could  you explian to me what is chemically going on to make the water content not constant? Or link some resource that can support that idea?

That would be incredibly helpful.

Thank you.
