IoT sensor devices are often powered by batteries. Nowadays, energy harvesting (EH) technologies even make possible the battery-less solutions to a sensor device equipped with a low-power radio and processor module. EH-powered sensor devices make an IoT network a true autonomous system with many years of operation; however, they are often used in certain conditions where EH is possible. You will learn the scenarios when EH-based wireless networking is suitable to be used.
- [Narrator] EH, which stands for energy harvesting,…is the process in which energy is captured…from the ambient environment…and converted into useful electric power.…The use of EH-based networks,…consisting of self-powered IoT end devices,…mainly came from the needs for IoT applications…for a long-term operation.…One solution to this energy harvesting based IoT network…is the use of energy harvesting technologies.…
Once the energy is harvested, energy can be stored…in a lithium-ion, or thin film battery, or a supercapacitor…as a power supply for other electronic components…on a sensor radio board.…On the IoT end device, the power can still be generated…or stored by energy harvesters.…The use of energy harvesters on an IoT device…enables the so-called "self-powered" IoT devices,…and it creates a whole new range of low-power IoT networks,…that can last for a long period of time.…
The EH-based networks can be used…in many application domains,…such as smart home, building automation systems,…as well as general machine-to-machine communications.…

4/19/2017Ryan Hu begins by introducing wireless networking for IoT, and going over the basics of wireless communication and wireless networking. Next, he presents and compares the underlying wireless networking technologies in terms of system architectures, communication paradigms, performance, and use cases. Then, he explains how to integrate various networking technologies into an IoT system. To wrap up, Ryan discusses the use of low-power wireless networking in a typical lighting control system for both smart home and smart city environments.
