In the history of
cars, there have been many accidents, and a lot of those accidents have been
because of the difficult act of reversing. You have probably experience this as
well, for whatever reason, and have probably been frustrated by it.
One of the many
available options in combating this problem is with the aid of a parking
sensor.

What It Does
Also known as a
backing sensor, or a PDC—Park Distance Control—a parking sensor is a sensor
used in determining the proximity of an object to the vehicle it is attached
to. When the vehicle comes to close to an object, it sets off an alarm which
instantly warns the driver of his or her closeness to an unseen object. The
system generally relies on the reflection of sound waves to pinpoint the
position and proximity of an object.
The Basic Types
There are generally
two types of parking sensors: electromagnetic and ultrasonic.
An electromagnetic
parking sensor mainly deals with slow movement, namely a vehicle slowly and
smoothly reversing towards an object. The alarm grows louder the closer the
driver moves toward the object. These sensors often do not require any drilling
to be done on the car, only offering a design that allows it to be mounted
discreetly on to the inner part of the bumper.
The other type is
the ultrasonic parking sensor. These are sensors attached to the front and/or
rear of the vehicle’s bumpers. They measure the proximity of nearby low
objects. The warning system depends on the speed of the vehicle and the closeness
of the object, either being visual or audible. The variation in the warning
indicates to the driver the general direction and distance of the object.
Rear sensors are
generally activated automatically when the car goes into reverse. Front
sensors, however, are usually activated manually, then deactivates by itself
once the vehicles reaches a certain speed.
Why People Love It
Many people find
parking sensors kit as a useful and fairly inexpensive alternative to the high
class backup cameras. Parking sensors take up less space and are usually almost
virtually invisible, thanks to their size and ability to be hidden behind
bumpers. They can also be adjusted so that they do not suddenly activate during
slow moving traffic—something that would surely drive you and your passengers
mad.
Depending on what
you prefer, you can have one of two types of parking sensors. Some people find
ultrasonic parking sensors to be a bit too fiddly to deal with, as some of them
involve installing more than one sensor in different areas of the vehicle. Most
consumers says that the electromagnetic parking sensor. Despite its simplicity,
it is fairly low maintenance and requires less effort for installation.
In many prevalent
opinions, an alarm-inducing parking sensor is better than a back viewing
camera, as the sensor will tell you if you are getting too close. A back view
camera will make you rely on your eyes only; sensors force you to listen as
well as look. As a parking aid, they are well worth their price, allowing you
to avoid even minor bumps while reversing. They can be considered as a useful
tool for both new and experienced drivers.
