What is the function of a parking sensor?

The functions of a parking sensor include: 1. Accurately measuring the distance between the rear of the vehicle and obstacles; 2. Emitting rapid warning sounds when reversing to a dangerous distance to alert the driver to brake; 3. Repeatedly issuing voice warnings to remind pedestrians to be cautious. The components of a parking sensor consist of: ultrasonic sensors, a controller, and a buzzer. The usage method of a parking sensor is: when the vehicle is in reverse gear, the parking sensor automatically activates. The alarm emitted by the parking sensor is a beeping sound at a certain frequency, and the frequency increases as the obstacle gets closer. When the beeping sound becomes increasingly rapid and is accompanied by a continuous tone, it indicates that the vehicle is very close to the obstacle.
The reverse parking sensor is such a practical gadget. I haven't been driving for many years, but since installing it, I feel much less stressed when reversing. It basically consists of several small sensors mounted on the rear bumper. When you shift into reverse gear, these sensors scan the rear like eyes. If there's an obstacle, such as a wall, pillar, or even a small roadside flower bed, it beeps to alert you. The closer you get, the more urgent the sound becomes, giving you time to stop and adjust. The scenario I encounter most often is in crowded residential parking lots, where cars and people are packed tightly. It has helped me avoid scraping other cars or being hit by suddenly appearing electric scooters multiple times. Many new cars now come with it as standard equipment, and retrofitting older cars isn't expensive either. Choosing one with distance display makes it even more useful. In short, for new drivers or those like me with limited experience, installing one makes reversing much easier, saving the constant worry of checking mirrors to avoid accidents.
