How do I measure the current consumption ??
The program is actually consist of a few steps of task to be perform.
Which also include changing of location of measurement but the between task time shouldn't exceed 8 seconds, it could be minimize to 4 or 3 seconds but it wouldn't make much difference I guess.
I am currently used HIGH interrupt as when the button is press then wake up. "attachInterrupt(1, wakeUpNow, HIGH);"
It is intended to be used like once a day so the used of LED and buzzer is only use during the performance of task so I hope to keep it the way it is.
Is the sensors other component still consuming the power even when arduino sleep?
