Sorry about the confusion on grounds, the triangle connection is simply meant to indicate a common connection which will be incorporated into a plane, not a ground connection. I'll see what I can do about getting the reference designators straightened out.
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.
