In addition to tracking temperature and light, his device has a particulate sensor that can detect small particles like pollen that can disrupt sleep for people with allergies. A “smart alarm” can wake a person up at the right time in their sleep cycle, like early forerunners in the space from several years ago like the Zeo.
The whole package contains three components. There’s the beautiful spherical sensor, and then a small clip-on called the “Sleep Pill,” that attaches to a person’s pillow and contains a six-axis accelerometer and gyroscope to track tossing and turning. It communicates with the sphere through Bluetooth Low Energy and ANT. There is no pairing or syncing necessary like there is with other wearables like theMisfit Shine, another great product that tracks physical activity on top of sleep.
The last component is a mobile app, of course. It awards a sleep score out of 100 based on the sensor data tracking night time disturbances and ambient light. Sense will give a breakdown of your score and help you start to notice patterns that might be interfering with your sleep.
