HDC1010: HDC1010 in Fluids

Part Number: HDC1010

Hello, 

Can The HDC1010 sensor work in mediums other than air? In that case, does the calibration need to be adjusted? 

What are the main parameters that affect the drift of the accuracy of the sensor?

Thanks,

  • Taoufik - 

    As humidity changes in an environment (we generally assume air), the polymer begins to absorb/shed water molecules from that surrounding (air) environment, which alters the dielectric constant of the capacitor sensor. 

    Do you mean a different atmosphere all together? Would you perhaps elaborate a bit more as to the operating conditions / your goals in the application?

    Josh,

    What I have in mind is to use the HDC1010 to measure water content in some fluids.

    Thanks,

    Dear Taoufik - 

    The HDC devices are relying on moisture in the air to operate correctly. They are not meant to be immersed in anything.

    I have moved this over to another Forum (for FDC, PGA, etc. devices) where they may have some thoughts on using those parts. 

    I would imagine a prox sensor reference could be repurposed into a liquid discernment, if the tech allows.

    Hello Taoufik,

    For measuring changes in concentration we have typically seen ultrasonic devices being preferred. We have a user who has done extensive analysis on the TDC1000 product and can be found here https://www.element14.com/community/groups/roadtest/blog/2015/12/27/ti-ultrasonic-sensor--liquid-identification-and-concentration 

    Let us know how we can help!

    Thanks,

    Arjun
