The Beddit Sleep Monitor from Misfit Wearables is a sleep monitor made of a thin-film sensor that is placed under your bed sheet. The Beddit Sleep Monitor enables you to better understand your sleep cycles and quality by measuring your total sleep time and a number of physiological signals, including respiration, heart rate, movement, snoring, and ambient sound. This data is transmitted wirelessly via Bluetooth to your compatible iOS device, where it is stored and analyzed for your review on the free Misfit app.
