Turn on Ultrasound sensing

Ultrasound sensing takes you to another level of convenience by making 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 should discontinue as soon as the ultrasonic noise stops.

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.

Learn about your commute
