How to measure power consumption of Jetson TX1?

532 Views Asked by At

I'm trying to measure power consumption of NVIDIA's Jetson TX1 system.

I tried the following command:

$ watch cat /sys/devices/platform/7000c400.i2c/i2c-1/1-0040/iio_device/in_power0_input

I guess 0 in in_power0_input means to measure the whole system's power consumption.

But I don't know what the result of the command means. Is this in watts? (maybe not because it's huge number) or any other unit?

in_power0_input command result

  • Or if there is any other way to measure power consumption of the board, can anyone let me know?
