Example Concept: Power efficiency in IoT edge devices can be enhanced by employing duty cycling, which involves putting the device into a low-power sleep mode when not actively processing or transmitting data. Additionally, using energy-efficient communication protocols like BLE (Bluetooth Low Energy) and optimizing data transmission intervals to reduce unnecessary power consumption are effective strategies. Selecting components with low standby power and leveraging edge computing to process data locally before sending it to the cloud can also significantly reduce energy usage.
