The article mentions 8/20 surge pulses as 8ms/20ms. That's wrong. The time scale is in microseconds. A pulse of 8kV with 20ms decay is a *very* large energy. TVSes are capable of absorbing power up to 400~5000W, depending on the model, but a 20ms pulse would require a much larger device.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
