Ultrasound sensing helps make daily interactions with your Google Nest display, Google Nest Mini, and Google Nest Wifi point easier. Have your touch controls automatically appear when you get close to your speaker or display. Get a view of your cooking timer with easy-to-read numbers when you're across the room. Whether you're near or far, you can get more help and control at a glance when Ultrasound sensing is turned on.
How Ultrasound sensing works
Ultrasound sensing uses your Google Nest device's speakers and microphones to determine whether a person is approaching the device. Your device's speaker will emit soft, inaudible ultrasonic pulses. These pulses are reflected off of nearby objects in the room and the microphones detect these reflections.
Note: Occasionally, other things in your home environment may cause ultrasonic noise and may disrupt Ultrasound sensing for a brief period. This disruption should discontinue as soon as the ultrasonic noise stops.
Explore Ultrasound sensing features
Google Nest displays
Easily view your notifications
If you have personal results and Home screen and notifications on your Nest Hub display turned on, Ultrasound sensing will show pending notifications on the ambient screen if you're nearby. For Nest Hub Max displays, if you have enrolled in Face Match and have personalization turned on, notifications will show when you are Face Matched by the device. If you're not enrolled in Face Match but you do have notifications and personalization turned on, Ultrasound sensing will show pending notifications if you're nearby.
Get a better view and control of your timers
When you set a timer and Nest display detects that you're nearby, it will automatically show your touch controls so you can easily control your timer. If you're across the room, your timer will be displayed in a larger font to help you view it more easily.
Stay updated on the daily weather
When you ask for the weather, you can get detailed weather information and an hourly forecast when you're near the display. You can also get a view of the day's weather in larger letters if you're farther away.

Ultrasound sensing and your privacy
The Ultrasound sensing feature is performed on your device and is used to adjust your speaker or display to make it more glanceable and easier to control based on your proximity to the device. No motion, proximity, or presence sensor data is sent to the cloud.
