Startup unveils ₹25,000 speaker that uses a radar to help people sleep better

US-based startup Anker has unveiled a new ₹25,000 speaker that uses radar to help people sleep better. The device, SleepLab Pro, uses 60GHz radar to monitor heart rate and breathing from the bedside and figures out which sleep stage the user is in. It can also figure out which sounds and lighting routines help users sleep better.
