    Details: 
    Hi,

    The manufacturer part number is given as SHT21, but Sensirion's SHT21 products have a sixth character indicating the output mode:
    SHT21D
    SHT21P
    SHT21S

    Does this Newark part number correspond with the Sensirion SHT21D part?

    Thanks,
    Scott

    A: 
    The supply voltage of SHT2x must be in the range of 2.1 – 3.6V, recommended supply voltage is 3.0V. Power supply pins Supply Voltage (VDD) and Ground (VSS) must be decoupled with a 100nF capacitor. For more information, please refer page 6 of 12 in the following link.
    For SHT21, two evaluation kits are available with Newark part numbers 20T1171,20T1170.
