HDC1010: Sensor calibration (HDC1010) after 10 years

Adrian Chmiel

Part Number: HDC1010

Hello,

How is look situation with calibration of HDC1010 after 10 years of work? It's needed or not?
I cannot find this information nowhere.

Adrian,

The HDC1010 can be expected to drift +/- 0.25 %RH/yr under normal conditions (20% - 50% RH and around 30C) as specified in footnote 12 of table 7.5 in the datasheet. So in 10 years you could expect roughly 2.5 drift in %RH reading. The device does not support re-calibration.

If this is a new design you should take a look at the HDC2010, this is a newer, lower power, device with a smaller footprint. The 2010 is also available at a lower price. The drift on the 2010 is the same as the HDC1010 as well.

Best Regards,

Brandon,

Thanks a lot, but I have one more question: how is look accuracy in long term for thermal sensor?

Best regards

Howdy Adrian,

Can you let us know the application? Also, to verify, your'e inquiring about the temperature drift performance after 10 years, is this correct?

Best Regards,
Matt

Hello,

We plan use sensor to check temperature gradient in open space, so we use few pieces of HDC.

So my question is, how will look temperature measurment error affter 1 year and them affter 10 years.

Hi Adrian,

Thanks for the information. Since this information is not included in the datasheet, I will need to forward this inquiry to members within our team.

Best Regards,
Matt
