Facebook's Prineville, Ore. facilities manager worked on a Bluetooth link to report stats from an individual server.
But a more ambitious effort--that won the prize--worked on a sensor network to report details from many servers. I have no other info on it, though.
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.
