DESCRIPTION
Working Principle:
This is a mini ultrasonic levitation device that can suspend foam balls. The device consists of a single chip microcomputer, a driver chip and two ultrasonic probes.
Mainly used for students or DIY electronics enthusiasts to learn about ultrasonic standing wave suspension.
It is not supported to control the floating object to move up and down.
Working principle: Ultrasonic standing wave levitation is through the existence of a certain distance between the ultrasonic transmitting end and the reflecting end (or another transmitting end) (called the harmonic cavity distance), and the transmitting wave and the reflected wave (or another sound wave) are continuously superimposed to form a standing wave. The sound wave force on the object at the node of the standing wave overcomes the effect of gravity and finally achieves the effect of suspension.
Working current: <100mA.
Micro USB 5V power.
Package includes:
1 x DIY KIT.
