Team,

With self heating on, how hot will device be in 60C ambient?

Thanks

Hi Victorija,
When you mean self-heating on, you mean the internal heater?

Regards,
Jose

Hi Victorija,
As explained in section 7.3.3 of the HDC2010 Data Sheet, enabling the heater is recommended only for ambient temperature from -40C to +85C.
Therefore 60C should be ok.
You can read the temp using the right register to determine how much is the increase, we don't quote a number on the data sheet since this increase will depend on IC (nominal vs. weak vs. strong).
Very roughly speaking for a 60C ambient temp you could have a 110C-120C reading once the heater is enabled.

Regards,
Jose
