Temperature read is unstable

Help and Troubleshooting
#1

The readings from the temperature sensor are somehow unstable. This graph tells the whole story:

The device is sitting flat on my desk and the room is at a constant 25C.

Is my unit defective or is there a way to get this stabilized?

Cheers!

The temperature going up and down is very strange.

  • Over what time of period was that taken?
  • Are you getting these directly using HAL or you are using CORE ?

I will investigate more on this.

Hi!

It’s over a couple of days. The data is available through this Excel sheet:

I query using the Javascript Core API.

Hi,

Nailed it. I used Object.assign to set device sensors state object. However, Pressure and Temperature sensors both exhibit temperature property in their respective readings. So this explains this “jumping”. It’s not a device issue but rather some kind of race condition on setters.

Cheers,
