There are so many clever gadgets available on a market, which can improve your life in just few steps.
Nest Smoke Alarm and Carbon Monoxide is something completely new in interior world, but can easily impress anyone with its stylish design and intelligent options.

From the Press Release:

As Nest founder and CEO Tony Fadell noted in the company’s press release, “we’ve reinvented the smoke alarm, because safety is too important to be annoying.”

Nest started from scratch in designing its own smoke alarm, knowing that there had to be more to the device than being set off every time you leave the chops in the grille too long. He was thinking "Instead of only howling about danger, why doesn’t it tell you that you’re safe? Why can’t you go to bed knowing you’re protected? And why can’t it message your phone if something’s wrong? Why can’t it be better?".
Nest Protect lights up in different colours and speaks with a human voice, telling you where and what the danger is. And it won’t just start yelling at you—Nest Protect gives you a friendly Heads-Up before turning on a loud alarm.

It also tests itself constantly and lets you know it’s working before you go to bed. Just look for a quick green glow when you turn out the lights. 
Nest Alarm is linked to your phone and you are able to check battery or sensor status from your phone or learn what to do in an emergency. 
Nest Alarm senses carbon monoxide and connects to your Nest Thermostat through your Nest Account. So it can automatically shut down the furnace, a possible source of CO poisoning, when the carbon monoxide alarm goes off.

All in all the Nest Protect is a new way to protect your house and your family from the dangers of fire and carbon monoxide
