The smoke sensor in the Nest Protect is different than any other smoke alarm we've looked at. The unit uses a split spectrum sensor, a special type of photoelectric sensor, which is designed to detect both smoky and flaming fires. The Nest Protect also has a built in a carbon monoxide sensor and will sound an alarm if it detects dangerous levels of the invisible, odorless gas which can be lethal if you breathe it for too long. To help cut down on false alarms from steam and burnt toast, the Nest Protect also uses humidity and heat sensors. We tested the detection capabilities of each smoke detector in our comparison by spraying test smoke from an aerosol can directly at each one from 5, 10 and 15 feet away. When we tested the 5 and 10 foot mark, the Nest Protect sounded its alarm after 18 seconds.

Avoid installing them in kitchens or rooms that have steams like saunas and bathrooms to prevent false alarms. Do not install smoke and carbon dioxide detector in breezy and ventilated areas like in front of electric fans, air conditioners, windows and doors. They may pick up smoke that originated in other places or the fresh air might obscure the reading, preventing the device from setting off when it should. Install them on a high wall or in the ceiling because smoke and fire rises. Having mentioned price, you might as well consider testing one of these so called smart smoke detectors. Some of these can be turned off by waving your arm at it in case it is accidentally set off. These smart detectors also give out a preliminary warning tone that tells you there’s smoke somewhere in the house, and gives you a chance to act. Other than that, smart detectors are also connected in a wireless network, and are able to talk to each other. So if a fire occurs in the basement and you’re in the bedroom, these smart little things will still sound the alarm wherever you are in the house. Stopping the alarm by waving however won’t work wirelessly. You’ll have to wave at the smoke detector that actually detected the presence of smoke before you could stop it.
