Sleep Sensing: Soli
A closer look
Video: Demo of how Soli works.
The Soli sensor senses motion through radar by
emiing a broad beam of radio waves. When an
object, such as a person, moves within the
beam, energy is reected back to Soli’s antenna,
so it knows you’re there. Soli can detect subtle
movements, such as your breathing, by
detecting changes in reected energy.
It’s the same tech that’s used for Pixel 4’s
Motion Sense. Now it’s being used to power
Sleep Sensing, Motion Sense, and Quick
Gestures on Nest Hub (2nd gen).
