The Chinese are merely copying with assistance from US veterans ( as reported here like this Mr. Sparks, ex Delco ) made homeless by Wall St.
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.
