Nest introduces the revamped Nest Protect

An all-new Nest Protect has been introduced by the company, bringing some new features and several safety improvements to the device. This time around Nest has included a new smoke sensor, new safety features, and the ability to hush the Protect right from your smartphone.

The Nest Protect can also now detect whether there is a fast or slow burning fire present, thanks to its new split-spectrum sensor. Priced at $100, the next-generation Nest Protect will be available starting in July 2015.
