HDC1080 / Figure 17 of datasheet

Other Parts Discussed in Thread: HDC1080

Hi Team,

I would like to confirm about Figure 17 of HDC1080 datasheet.
I believe red part(vertical axis) shows relative humidity(%) and blue shows typical RH accuracy(%RH).
Is my understanding correct?



If the answer is yes, there isn't RH offset values in Figure 17.
I would like to know RH offset values that sensor is exposed to less severe conditions for duration 500 hours.

Best Regards,
Yaita / Japan disty

    Dear Yaita-san,

    Yes, I confirm that your understanding is correct: Figure 17 in the  HDC1080 datasheet shows the typical RH accuracy in function of the actual relative humidity (vertical axis) and actual temperature (horizontal axis).

    Regarding your second question, HDC1080 doesn't show any significant offset variation if it is kept in recommended conditions:

    •    Recommended humidity operating range is 10% to 70% RH;
    •    Ambient Operating Temperature -20ºC to 70ºC

    Please let me know if this answers to your question or you need further information.

    Best regards,

    Carmine
