When smoke alarms are annoying, we get frustrated -- we take out their batteries or tear them off the ceiling. And that puts us at risk. So we reinvented the smoke and carbon monoxide (CO) alarm. Nest Protect quiets down when you wave -- no more swinging towels or brooms -- and messages your phone when its batteries run low. It speaks with a human voice, telling you where and what the danger is, and gives you a friendly Heads-Up before turning on a loud alarm.
