Part Number: HDC1080

Hello,

I am using your HDC1080 sensor on Arduino boards with Arduino Library and formula from your product documentation.

I got following issues:

-Temperature offset value is generally up to 2 degree Celsius (compared to a reference)

-With 2 identical Arduino boards, humidity value measured is not idenitical

Any idea ?

Thanks in advance for your support

Hello,

Can you tell me what type of temperature reference you are using and where is it placed with respect to the HDC1080?

Have these parts been exposed to any chemicals or pink foam/pink ESD bags?

Hello,

Temperature reference is a digital thermometer into a closed room (20-25°C).

HDC1080 is soldered to the board (at 5mm of ARM processor).

No exposition to any chemicals or pink foam/pink ESD bags.

Hi Arnaud,

There might be a component on the board that might be generating heat. Could you please share the schematic?
