Ultrasound Switch / Light switch

Ultrasound Switch
Ultrasound Switch

The ultrasonic switch can emit the ultrasonic wave at a fixed frequency (such as once a minute), and determine whether there is any activity in the house by comparing the position information of the surrounding objects collected by the two adjacent launches, and thus determine the switch of the lamp to achieve the goal of energy saving.
The user can press the net cover to turn on the ultrasonic transmitter. The ultrasonic can be transmitted to the outside through the mesh on the net cover. The built-in chip will analyze and process the reflected acoustic wave information. Simple white design can match most interior decoration styles.
