How to read the Internal Temperature on a NAU7802

Sensors Force & Weight

Hi,

I have the NAU7802 breakout board and was hoping to get some advice before plunging down the rabbit hole. The Datasheet says the chip has an internal temperature sensor. Is there a reason the library does not support using it? Has anyone attempted to set the “TS” bit in Register 0x11 to enable the temperature sensor using the setRegister function?

Second unrelated question: I have read the datasheet and can’t seem to find out if there is any noise penalty for setting the sample rate to 320 sps as opposed to 80 sps or lower. Anyone have any experience? Thanks so much.

The temperature circuit is used to calculate the zero-offset at a given temperature…you could fiddle with the registers or edit the source files https://github.com/sparkfun/SparkFun_Qw … _Library.h https://github.com/sparkfun/SparkFun_Qw … ibrary.cpp for another purpose

As for the data rate/noise, I’d suggest simply testing to find out - report your findings here!
