How Much Distance is Left When the Parking Sensor Beeps Continuously?

[SanMarcus]

When the distance is within 30cm, the parking sensor will emit a continuous beep. Here is some relevant information about parking sensors: 1. Components of a parking sensor: It consists of ultrasonic sensors, a controller, and a display, among other parts. 2. Principle of parking sensors: Also known as anti-collision radar, as the most basic parking assistance system, it emits ultrasonic waves through the ultrasonic sensor. When the ultrasonic waves hit an obstacle, they are reflected back and received again by the ultrasonic sensor. The controller then calculates the distance between the vehicle and the obstacle based on the time taken for the ultrasonic waves to be emitted and reflected back. Finally, an alarm sounds to alert the driver with a rapid warning beep.
