The Nest Protect 2.0 is one of the many announcements the company recently made at an event in San Francisco. It's the next generation of the original smart smoke detector, featuring a range of slew of improvements that ensure safety is increased even more.
One of the biggest tweaks of the Nest Protect 2.0 involves a split spectrum sensor. The Verge explains how this is "a step beyond the single photoelectric in the original one. Nest says that ability to detect smoke with a sensor that can read shorter wavelengths is important because modern building materials can burn much faster, so the sensor should be able to detect smoke more quickly." The technology has also been redesigned to make the unit smaller.
