Amazon Echo Dot Smart Speakers Can Now Detect People in The Room
Echo speakers receive the function with which they detect people in a room.
The new Echo and Echo Dot Smart speakers can now use ultrasound to detect occupancy in your home and turn other connected devices like lights or your Fire TV on and off.
First mentioned at Amazon’s fall hardware event in September, the fourth-generation Echo and Echo Dot speakers can now emit an “inaudible ultrasonic wave” to detect if people are present in a room, The Verge reports.
You can turn this feature on or off in the Alexa app, where you can also set up occupancy routines to use this new ability to do things like turn lights on when you enter a room and then turn them off again when the room is off. empty.

You can also ask Alexa to play music or a radio station when motion is detected near an Echo device for a set period of time, and then stop songs after it’s gone.
The feature appears under Motion Detection in the Alexa app settings for each supported Echo device, and you can turn the feature on or off here.
This feature is similar to the newer Echo Show motion detection devices, but they rely on their cameras to know if there are people in the room.
Echo Dot Smart Speakers do not have cameras, so the device detects movement by emitting an inaudible ultrasonic wave that is reflected off nearby objects before returning to the device’s microphones.
