My wife bought me a watch for Christmas -- it looks like the control panel for a 747 -- it has so many knobs and dials that it's difficult to find the ones that tell the time (grin)
There's some sort of alarm function that goes off at 2:00am every morning -- I have no idea where I put the instructions -- so every night before I go to bed I have to bury the watch at the bottom of my sock drawer...
... I tell you, t=you wouldn't believe my life if you saw it as a sitcom on TV :-)
And of course it's always at night since batteries operate less efficiently at lower temperatures. Perhaps the need to latch the low battery trigger until a light sensor indicates it's no longer night time? ;-)
I have a watch that does that. Every so often I get it into a mode where it "meeps" every hour, and I have to find and read the manual (no small task, especially the finding) to work out how to switch the hourly "meep" off.
And they always seem to make the "meeps" at a frequency where your ears are not very directional...
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.
