@baldpolnareffart @phoronix I have two devices that would be ideal candidates: one is a Thelio, and the other is a 17" laptop with a dedicated Nvidia GPU. (The other laptops I have just don't pack a good gaming punch, and personally that's something I want to test extensively).
I'll look into their sensor capabilities this weekend.
