When designing battery-powered sensor devices, optimizing the power consumption of all components is crucial. While many sensors offer low-power modes, the generic sensor interface in Zephyr may not always utilize these modes efficiently.

In this talk, I will provide an in-depth look at how Zephyr’s Power Management Subsystem works, how to integrate it into your device drivers, and how it can be used to further reduce power consumption.

Using examples such as a battery level sensor and I2C sensors, I will demonstrate various strategies to manage and minimize a sensor's energy usage. There are multiple approaches to integrating power management within the Zephyr operating system, and I will discuss how sensor characteristics influence which method results in longer battery life. Achieving optimal energy efficiency requires careful consideration of several parameters.

Additionally I will compare different MCU's and their influence on Power consumption and how Zepyhr enables a quick and easy way to switch and compare results on different platforms.
