The internet of things (IoT) is a broad term for all sorts of interconnected gadgets that collect, share, and respond to data. The phrase may be muddy, but you’ve probably already encountered IoT. Consider a smart front door lock like August, for example, which connects with your smartphone and automatically unlocks as you approach your porch. Other devices, like Amazon Echo, can be used to control a bevy of appliances and electronics throughout your home. Still others, like the floor sensors, collect and analyze user data for health and wellness applications. Many of these devices are little more than high-tech conveniences, but among them are products focused on one of our most vulnerable populations: the elderly. And not a moment too soon.
