Ultrasonic ranging teaching experimental apparatus

An ultrasonic ranging teaching experimental apparatus belongs to the field of teaching experimental apparatuses. The ultrasonic ranging teaching experimental apparatus is composed of a frame, telescopic springs, a moving clamp plate, an ultrasonic ranging module, a controller, and a wire. The frame is composed of a small baffle, guide rails, and a fixed clamp plate. The moving clamp plate is composed of a threaded knob and a clamp plate frame. The controller is composed of a liquid crystal display, a box body, a main switch, a reset button, and a measurement start button. The two telescopic springs sleeve the two guide rails of the frame respectively. The moving clamp plate also sleeves the guide rails of the frame. The ultrasonic ranging module is fixed to the upper end of the fixed clamp plate of the frame. The controller is connected with the ultrasonic ranging module through the wire. Although the experimental apparatus has a simple structure, the experimental apparatus shows the principle of ultrasonic r
