I am using the energy profiler to measure energy consumed while executing a python script. The energy measurements provided by the profiler seems to be in mAh. I wanted to measure energy consumed in Watt hours and also in finer granularity. I was wondering if I could use the instantaneous power measurements given by the profiler and compute the energy consumed as the area under the power curve. I am not sure if it is fair to assume that the 0.25 second interval is adequate enough for computing energy consumed accurately.

Any thoughts/suggestions ?


Thanks

Yes, this is how you should do it.

0.25s interval is accurate for active apps that consume >100mA (>0.37W). In standby, the measurement gets overhead from fast measurements and you should use 5s interval. Do read Options>Help for details and check out the NEP webinar slideset.
