HDC1000: Calibration for accuracy

Part Number: HDC1000

Using HDCypar part for temperature and humidity measurement in our system.

The measurement values are 61% and 25'C, but should be 84% and 12'C as real.

How to calibrate them? just write 0x1000 @0x2 and read each 14bits and calculate by provided equations.

Pls. giude on this matter.

  • Dear Vrai - 

    Can you confirm that you are also trigger the measurements by executing a pointer write transaction with the address pointer set to 0x00?

    Refer to Figure 12 on page 13 of the datasheet, here: 

    If possible, also provide logic analyzer captures if possible, Saleae logic files would be handy if you have one of those and can provide. 

     

  • Dear Vrai - 

    if you have a moment to provide captures and confirm that you are starting the conversion, that would be great.
