The Protect measures both smoke and carbon monoxide and features several smart features, such as the ability to turn off an alarm with the wave of a hand. In addition to the US, Nest has also brought the product to the UK, where it will sell for £109.

Nest announced the alarm last month as a follow-up to its learning thermostat.
