I just thought of another example, HTML. I create a web page with HTML, it goes through 100s of differnet protocols but in the end it gets to my browser and renders correctly (usually). This is only one way, but maybe helps to explain what I mean.
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.
