HDC2010: Placement question for HDC2010

Part Number: HDC2010

Hi expert,

My customer is asking about the placement of the device.

We also refer the link of the app note ,

From the page 7 and page 8, shows some placement options, but we are not able to see what is the difference between and what to aware of.

Below is customer questions.

"We want to detect the environmental temperature and humidity. Could you suggest about the air flow ?

If we want to use single window of air flow, could you make some suggest ? For example, the size of the single window and the distance from the sensor, etc. What information do you need ? 3D stacked up ? Thanks."

Thank you,


  • Hi Oliver,

    The first few images on Page 7 are the placement options for the HDC2010 sensor. The main differences between the images are the different package options (DSBGA vs WSON). 

    In general, our humidity sensors’ sensing elements are very sensitive and efficient. A little opening is sufficient, assuming there is no filter membrane blocking the holes.
