Powering the Internet of Things via energy harvesting

April 3, 2017 OpenSystems Media

The push is on to add internet capability to everything, and the challenge for design engineers is to figure out how to power each of these IoT nodes. If there is an AC power line or conventional long-life battery available, the decision is greatly simplified, of course. But such power is unavailable in many cases, and energy harvesting can look like an attractive, free, no-headache alternative. However, there are many facets and limitations with this type of “free” energy, beyond the initial component cost. First, before even looking at harvesting as an option, it’s critical to put together a power budget. How much current and voltage will the IoT node need? What power is needed at each phase of operation? To get all of the answers to your power questions and to discover the latest green solutions, visit Avnet.com.
