Using the principle of ultrasonic ranging, the controller controls the sensor to transmit an ultrasonic signal. When the ultrasonic signal encounters an obstacle, an echo signal is generated. After receiving the echo signal, the sensor performs calculation through the controller CPU, and processes and judges it. The display shows the distance, bearing, area and other information of the nearest obstacle, and the buzzer (horn) sends the corresponding warning sound in time.
