PSoC is amazingly versatile. I'm most familiar with the PSoC 4 and especially 5LP: those are the parts with ARM Cortex-M0/M3 CPUs. For a quick overview of some of the things that you can do with PSoC 4/5LP, I recommend element14's 100 Projects in 100 Days.
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.
