We have a Atmega328 , that is in deep sleep. It used to wake up from an accelerometer detection of a move interrupt.
We have now discovered that the accelerometer detection is not working if you open a door slowly .
So , we want to check whats going on with the accelerometer every half a second .
Now we are in sleep mode,the deepest one, waking up on interrupt .
What if we wake the processor every half second, check the accelerometer for 250ms and back to sleep.
How can we estimate the current consumption then ? (its now less then 100uA)
How much this will add to the overall consumption ?
