I find that trend very interesting. That's the way it was a few decades ago. Everybod had their own manufacturing. Then everybody went on an outsourcing binge. It's interesting to see the the reverasal trend
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.
