HDC2010: Data consistency

Part Number: HDC2010

Is the data always consistent when I read all data (4byte temperature and humidity) in one read cycle?

What happens if the internal measurement overlaps with the readout?

Is the MEAS_TRIG bit set to "no action" directly after starting the measurement or only after the measurement has been performed?

  • Hi Paul,
    There shouldn't be any problem reading consistently the 4 bytes of Temp and Humidity.
    For programming examples please refer to the example code written for Arduino using the following link. In addition there is a training video that elaborates on the topics you have questions.

    Thanks for the answer. I guess the data is consistent! But the following question is still open:

    Is the MEAS_TRIG bit set to "no action" directly after starting the measurement or only after the measurement has been performed?

  • In reply to Paul Sveda:

    As explained on page 26 of the data sheet. Measurement trigger
    MEAS_TRIG description: Self-clearing bit when measurement completed.
