The goal of this project is to design a smart door/window sensor reducing power consumption(in deep sleep/standby) with a custom power latch. Optimizing the deep sleep power consumption of batterypowered smart devices ensures a long battery life cycle.

The current was measured with Nordic's power profiler kit, knowing that the current measured is less than the measurement range of this power profiler. I did several tests to verify the accuracy of the data. In any case the accuracy of the data, the consumption would be less than 200nA and this is a very good result considering that a similar device at a power consumption of 68uA.
