“Great weather again today. I’ve just got to get down to the beach to train a little. It’s going to be tight with the party tonight, so I’ll have to be quick. Let me just get my board and my keys... OK, let’s roll!”
But what about the kitchen window? And the garage door? I just know I’m forgetting something... But Helen’s mind is already at the beach. Good thing she has a team of little helpers at home: tiny sensors on the first floor of her house that detect when a window or door has been left open. In the future, they will even be able to remind Helen to shut them via smartphone app.
