Google Inc. bought Nest Labs, Inc. for $3.2 billion in cash.

According to the search-engine company, Google entered an agreement for Nest's acquisition but the transaction is subject to regulatory approvals within the United States.

The deal is expected to close within the next few months.

"We're thrilled to join Google," said Nest CEO Tony Fadell. "With their support, Nest will be even better placed to build simple, thoughtful devices that make life easier at home, and that have a positive impact on the world."

Google noted Nest will continue to operate as its own separate brand despite the acquisition. Fadell was also confirmed to continue to serve as Nest's leader.

According to Google, Nest has been credited for reinventing vital home devices such as smoke alarms and thermostats. Nest launched in 2011, and the Nest Learning Thermostat has been touted as a "consistent best seller." Nest recently launched the Protect, which is a dual smoke and carbon monoxide (CO) alarm.

"Nest's founders, Tony Fadell and Matt Rogers, have built a tremendous team that we are excited to welcome into the Google family," Google CEO Larry Page stated. "They're already delivering amazing products you can buy right now--thermostats that save energy and smoke/CO alarms that can help keep your family safe. We are excited to bring great experiences to more homes in more countries and fulfill their dreams!"

Fadell and Rogers have previously worked for Apple Inc. notably with the iPod division.

"A former Apple executive joining Google? That's big news," noted TUAW's Yoni Heisier.
