I used to work on panel meters that use DIP switches to change resolution (think add a digit). If anyone went inside, they could figure it out. All you had ot do was remember the original setting if this didn't work. Today, you take a picture with your phone before changing things.
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.
