Is there anything that can’t be connected to the Internet? For example, where I once wore a $10 pedometer clipped to the waistband of yoga pants, I now wear a $130 fitness tracker on my wrist. In the past, I just took a look at the numbers on the pedometer to see how many steps I’d taken; now I need to log onto an app on my smartphone to see how far I’ve walked and how many calories I’ve burned and even how well I’ve slept. Or, if I wanted to, I could turn on any light in the house from the comfort of my couch rather than get up and do so manually. And that’s just a small scratch on the surface of the phenomena that is known as the Internet of Things (IoT).
