Autonomous IoT devices are those that operate independently without any human intervention. These devices are typically powered by batteries or other energy sources and must operate efficiently to ensure long battery life. The power management system for autonomous IoT devices must be able to manage the energy consumption of the device and maximize its operational life. In addition to these techniques, the power management system for autonomous IoT devices may also include energy harvesting capabilities. Energy harvesting involves capturing and storing energy from the environment, such as from solar panels or temperature differentials, and using this energy to power the device. By incorporating energy harvesting capabilities into the power management system, the device can potentially operate indefinitely without the need for external power sources.
