Hello,
we are using the HDC1080 and see a worse accuracy as given in the datasheet.
The measured temperature differs by about 1°C and the humidity by about 10% between the sensors (at nominal 20°C / 40%).
We have 7 sensors located in close proximity (with one SCD41 from competitor) in a climate camber with ventialtion. They are all soldered on flexible PCBs with about 30mm distance to the mainboard for reading. So due to the fantilation and distance to heat sources we should not have any heating transfer to the sensors caused by some other devices. We already connected all sensors FPC's to the next mainboard and see that the error is moving with the sensor. So there's no relation to the mainboard or position in the chamber
What else could have an impact on the sensors which could result in such bad accuracy?
Thenks,
Helmut
