It has outstanding detection capabilities and innovative alerts that let you know exactly what threat your home is facing and how to proceed. It’s intuitive to install and its high compatibility with third party products is a huge selling point as well. The only gripe we have is the relatively short warranty. 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.
