2.2.1. EFR32 Low-Power Modes

According to Hyung-Sin Kim et al. [14], although the idle current of each hardware component is provided by its datasheet, the idle current of a sensor node may be impacted by many additional factors, making it significantly greater than the sum of the datasheet values [14]. The MCU of the Cookie, as part of the EFR32MG12 family, has a variety of low-power modes available. These modes allow the SoC to save energy by reducing the power consumption of the processor when it is not required to display its complete functionality. These modes are depicted as follows [15]:
