What Is the Parking Sensor and How It Works?
Today, many are interested in what a parking sensor or a parking radar is and what it is for. It is a device designed to facilitate difficult parking in an urban environment. Using a signal or image, it warns of all kinds of obstacles and calculates the distance to them. Parking sensor is worth buying not only for beginners but also for experienced drivers. After all, there are situations when, having parked at a distance from the car, upon returning you find that it will be very difficult to leave without damage. In this case, parking sensors will help you avoid collisions in conditions of limited manoeuvrability. To know more about this useful technology, keep reading this article.
What is the parking sensor?
So what is a parking sensor and how it works? Such a device is a system with such components as the main unit, sensors, and a distance indicator. The block organizes the work of all components and converts the incoming information into audio or visual signals. The sensors are located on the front and rear bumpers of the car. They emit ultrasonic waves that are reflected from objects falling into the area of action. The reflected wave is received by sensors that transmit these signals to the main unit. The distance to the obstacle is calculated depending on the wavelength, and this information is issued to the driver. In the absence of a display, you have to navigate by the sound signal of the beeper.
Main types of parking sensors
Today there are many models of such devices, differing in the number of sensors. They can be divided into the following types.
With 2 sensors. It will differ in its low price, but it should be borne in mind that a given number of sensors may not “see” small objects located outside their range of action.
With 3-4 sensors. This parking radar is considered the most optimal in terms of value for money. With such a number of sensors, the appearance of a “blind” zone is excluded.
With 6 sensors. In this case, 4 of them are installed on the rear bumper and 4 on the front. Some models of parking sensors are equipped with a special switch, it activates the system in front or behind the car.
With 8 sensors. They attach to the rear and front car bumpers. This is one of the most expensive and reliable models. 4 sensors are installed on the front bumper and 4 on the rear. Such an installation excludes a blind spot in a confined space, the parking sensors will not miss even large details.
Type of indicators
Before you buy a parking sensor, you need to decide on the type of suitable indicator. After all, it is with its help that the driver learns about the presence of an obstacle and the distance to it. In models without a screen, the notification occurs using sounds emitted by a beeper, and the closer the object, the higher the frequency of the signals. In the case of the closest approach, the sound will be almost continuous. If there is a screen, the distance is displayed in the form of scales showing the conditional location of the machine, and if the device has a metric system, the distance to the obstacle will be displayed as numbers indicating meters and centimetres.
