HDC1050 vs Sensirion's SHT21

Other Parts Discussed in Thread: HDC1050

Hi,

We are currently using Sensirion's SHT21 on one of our designs. I'm trying to compare it against the HDC1050 and would like your clarification on the following:

- What level of protection is it required? SHT21 is recommended to be mounted along with a protective cap that features an hydrophobic membrane that protects the sensor against dust, contaminants and such. Is HDC1050 package and sensor "interface" design to withstand all this by itself?

- Are you planning to release a new version with lower Vcc? I mean 2.7V seems too short for coin battery operated sensors (for example). Being able to use the part down to 2.5V or 2.2V would ease the power requirements a lot.

- Any plans to release new versions with improved accuracy (or at least with an accuracy curve more 'flat')?

Thanks!

  • Dear Jose

    The protective cap is needed only if the environment is very dusty.
    In that case you can use the same that you are using today.

    At the beginning of next year we will release a device that is pin-to-pin and software compatible with the HDC1050 with improved accuracy and much more "flat" accuracy vs. humidity curve

    We also have a plan to release a device with lower voltage supply range in the next future.

    Best Regards
