Compared to the competition, Nest Protect 2.0 is by far the best smoke and carbon monoxide detector on the market today. Whether it’s activating the convenient in-app “silence” feature when needed or its full integration with other smart devices, Nest’s second-generation smoke detector comes with all of the bells and whistles.
With the traditional dome-shaped smoke detector notorious for false alarms when you’re just cooking, it’s time for the 21st century home to get a much-needed upgrade. Nest Protect 2.0, whether you’re Wi-Fi connected or not, will flash yellow/orange and say, “Heads up. There’s smoke/CO,” if there is any indication of trouble.
If it’s a false alarm, like leaving the pizza in the oven for too long in your studio apartment, Nest’s companion app allows the user to manually switch the detector to “silence” mode. If there’s an emergency, Nest Protect will flash read and say, “Emergency, smoke/Co detected.”
Capable of speaking to other units, multiple Nest Protect detectors are designed to simultaneously issue a loud warning if just one device senses increasing smoke or CO levels. So if a small fire starts in your kitchen, your Nest Protect located in your bedroom will go off and warn you accordingly.
With built-in sensor technology designed to sense electrochemical CO, heat, and humidity, this is one smart detector. Even better, the new Protect 2.0 version has been upgraded with a split-spectrum sensor capable of detecting the speed of a spreading fire.
Outside of the impressive smoke and CO detection technology, the Nest Protect 2.0 is designed to seamlessly integrate into a modern home. Available in a white or black finish, Protect features a stylish square design and a stainless steel mesh cover.
Version 2.0 creators made sure to showcase the alert status with colorful LED’s circled around the on-off button. The stainless steel mesh cover allows for access points for both CO and smoke.
Whether it’s connecting to the family of Nest products (Nest Learning Thermostat, Nest Cam) or automating with IFTTT, Protect provides the one thing every homeowner should have: peace of mind.
For those interested in upgrading to a state-of-the-art super-smart detector without compromising aesthetics, the Nest Protect 2.0 is a fantastic choice. Now all you have to do is decide whether you want the battery-powered model or the hard-wired version.
Ideally, when you buy a new smoke/CO detector, you hope to never have to use it. But when that time comes you’re going to want one that’s reliable and sturdy. The Nest Protect is all of this and more. If you’re looking to upgrade your smoke detector, I would highly recommend trying the Nest Protect from Google.
