    Hi Vijiay,

    We offer FMCW radar, not TDR. We don't have anything available at this time for surface classification, which is what you appear to be asking about here, but there is ample literature available online describing how you could do something similar. Good luck!

    Best,

    Nate

    Dear Vijay - 

    Have you considered a device like the HDC3022 (digital temp and %RH sensor)? the rest of the PCB could be conformally coated, and this device has a hydrophobic PTFE filter installed, which allows water vapor through, but not anything else larger than 100nm.
