Google Google Protect (2nd generation)

The Google Nest Protect (2nd generation) is a smoke detector that thinks, speaks, and sends alerts to your phone. The Nest Protect has been redesigned from top to bottom. It features a Split-spectrum sensor, automatically tests itself, and lasts up to ten years. The Nest Protect is also the first household detector that allows you to silence the alarm with your smartphone without needing additional hardware. And it tells you what the problem is and can even send an alert to your phone. If Nest Protect detects smoke anywhere, it gives you a spoken warning, and if one speaks, they all speak. This way, everyone in the house knows what's happening.
