Nest Protect

A smoke and carbon
monoxide alarm that thinks,
speaks, and alerts your phone.

There's never been a smoke and CO alarm quite like this. Nest Protect looks for fast-burning fires, smoldering fires, and carbon monoxide. It also speaks up when there's a problem, can be hushed from your phone, and it will even message your phone in case you're not home.
