    Hello,

    I have a couple questions:

    • The two data pictures say SHT85, what commands are you sending to the HDC3020? Just 0x2400 for a 1-shot measurement?
    • So you were able to communicate with the HDC3020, and then it stopped communicating at all? At what RH & Temp conditions has this occurred? Do you see any evidence of water condensation creating a short on the sensor's pins?

    Thank you
