Amazon's Halo Rise is a $140 bedside sleep tracker that works by sensing you breathe

Amazon wants to help you get better understanding of your sleep, but knows that many of us hate wearing something to bed just to track our rest. That's why it made the Halo Rise — a bedside lamp and sleep tracker that works without a camera or microphone to track the person resting closest to it. It'll also use machine learning to detect what sleep zones you're in and will cost $140 when it's available later this year.
