• Requirement details: Relation Envir. temperature VS Jetson performance
Hi, I had tested a Jetson Nano inside a IP65 encolsure box in 2 differente cenarios:
- Indoor: where the environment temperature is stable at 23/24ºC. The temperature inside the box stabilized at 35ºC and CPU/GPU temperatures at around of 50ºC. The resultant average power consumption was 4.0 Watts.
- Outdoor: where the environment temperature is stable at 20/25ºC. The temperature inside the box changed between 40/44ºC and CPU/GPU temperatures at around of 57ºC. The resultant average power consumption was 4.6 Watts.
In both cenarios, the CPU, GPU usage was the same, around of 50%.
My question is:
Why is Jetson Nano DevKit consumming +0.6 Watts outdoor comparing to indoor cenario? Is this +15% of power consumption justified by the higher enclosure temperature of the air? How can I justify this increase, knowing that in both cenarious the software was the same (something based on deepstream test 2 + python bindings)?
