Calling this a "design article" is a bit of a stretch isn't it? Lots of single-page ads are more "educational" than this. But from a marketing guy's perspective, this is a cheap way to get an ad in front of engineers. But let's call it what it is, please.
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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
