@Max, No problem and that's quite impressive! To not have a cell phone in this day and age. I tip my hat to you sir. Me on the other hand... I have a cell phone and simply don't return calls and such when I don't feel like it which sometimes leaves people offended.
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.
