Continuing the discussion from What does each temperature zone mean: AO, PLL, Thermal:

At now, I could not understand if “Thermal” parameter presents the temperature of neighbor environment of if it measures a specific zone of Nano SoC or expander.

I need to know the environment temperature around Jetson Nano and this “Thermal” parameters presents usually 25

ºC which seems to be the environment temperature. is it or it’s just a coincidence?

Image as a example:

Are you asking the “thermal” which is 31.25 in your picture?

Right.

That is the weighted value from CPU and GPU temperature. That is why it is 31.25C.

So. the “thermal” value is calculated like this:

thermal(ºC) = [CPU(ºC) + GPU(ºC)] / 2
      31.25 = [  32.50 +   30.00] / 2
      31.25 = 31.25  [✔]

(according to the data in the above figure)
