Nest smoke detector

This is the Nest Protect a smoke and carbon monoxide detector. Instead of simply beeping, it tells you exactly what and where the problem is, and you shut it up just by waving at it. It will last for years on six AA batteries, and ping your smartphone when they need to be replaced. And it serves as an activity sensor for the Nest Learning Thermostat, letting it more accurately adjust your heating and cooling as it learns when you’re home and away. Particularly the black one, which dramatically sets off the multicolor LED ring around the button and lends a touch of ‘80s flair to Nest’s logo. “We’re about reinventing unloved categories,” says Fadell.
