HDC1008YPAT Environmental Testing

Other Parts Discussed in Thread: HDC1080, HDC1008

Does information exist anywhere that details environmental testing for these sensors?

I've read the part about avoiding volatile chemicals, but what about more common environmental elements (i.e. salt content in the air in coastal areas)?

I am looking at using this product with a volume of roughly 300,000 pieces in the next year and don't want any surprises.  Any information that could possibly ease my concerns is appreciated.

    Hi Kory,

    This is a Temperature Forum. Let me move your thread to the correct forum.

    Hi Kory,

    We performed some test on common environmental elements. HDC1xxx survive to:

    • tobacco smoke;
    • oil smoke (mosquito repellent vapor, incense smoke);
    • cooking oil vapor;

    Hdc1xxx fail instead with following elements:

    • Des-infectant;
    • Glass cleaning detergent;
    • Air fresher

    Btw, for your project we warmly suggest to switch to HDC1080. It uses a new sensing element that improves the accuracy and the stability at high humidity value:

    www.ti.com/.../HDC1080

    It is in preview mode at the moment, but it will be released for the Mass Production at the end of this month.

    Please let us know should you need further information.

    Best regards,
    Carmine

    Carmine,

    Thank you for your response.  It is greatly appreciated.

    Can you please provide me with documentation of the testing that was performed?  I am interested in seeing the specific information from these tests.  I am looking for something that will ease my mind about putting this part into mass production in our product.

    The product in which I am using HDC1008 is extremely cost-sensitive.  I assume that even in high volume the HDC1080 will be more expensive.  Please correct me if this is an incorrect assumption.
