RichQ, Maybe the answer is continuing education or the Internet. Internet has a lot of free education on it now. I do think engineers are curious about the world and are usually passionate about finding out how things work, so they may be inclined to learn broadly on their own. Some are just heads down and not interested.
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.
