 ## Description
 The new Nordic Semiconductor's [Power Profiler Kit II (PPK 2)](https://www.nordicsemi.com/Software-and-tools/Development-Tools/Power-Profiler-Kit-2) is very useful for real time measurement of device power consumption. The official [nRF Connect Power Profiler tool](https://github.com/NordicSemiconductor/pc-nrfconnect-ppk) provides a friendly GUI with real-time data display. However there is no support for automated power monitoring. The puropose of this Python API is to enable automated power monitoring and data logging in Python applications.
