surprised to see the thumbnail picture you used is Blaise Castle folly in Bristol,UK. BTW it is not a castle at all but just a talking point folly in the grounds of a manor house now owned by the city.
Strangely exactly this picture is used on the Wikipedia page!
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.
