HDC1080 heater

Does the heater effect only the humidity sensor, or will it also change the temperature readings?

I assume both.  Also is the heater on all the time when enabled, or only during reads of the humidity sensor, temperature sensor or both?

    Hi Alan,

    The heater consists in an integrated resistive element that when is passed through by current, it begins to dissipate power, increasing locally the temperature of the device. This impact on both the temperature and the humidity reading.


    The heater is ON only during the conversion time. It means that the temperature increase is related to the output sampling frequency.

    Please let me know should you have any doubts or needs further information.

    Best regards,

    Carmine
