Hello TI,

I am using HDC3021DEHR this sensor for the temperature to Modbus convertor application.

I need NIST Certificate which is calibrated by ISO/IEC 17025 std.

Thanks you.

Hi Sagar,

You can request the NIST information on the HDC3021 product page. https://www.ti.com/product/HDC3021

We do not currently offer individual certificates.

thanks,

Hello,

Need Sensing element which is used in the HDC3021DEHR,

This one is needed for to mention in the datasheet of the product.

Thank you.

The temperature sensor is based on silicon transistor properties:

The humidity sensor relies on a moisture-absorbing polymer applied to the top of the IC that acts as the transducer.

Hello Ren Schackmann,

Thank for the sharing information,

It was helpful to understand the sensor working, as per our undersetting the sensor is working of principle on RTD , But which material is been used for sensing of the temperature that is Platinum, Nickel or copper or Any other, Let me know ASAP.

The IC temperature sensor technology is not RTD. The linked documents describe it is known property of transistor.
