Three Kinds of Parking Sensor

As we all know, automotive parking sensor is playing an important role in our driving life.In the past, only some advanced cars have been installed with back up sensor when in factory, but now with the development of car electronics, market of reverse parking sensor has become diversified. Parking sensor is more and more popular and installed in all kinds of cars. And some car lovers even make "DIY" sensors to decorate their cars. This article maily will tell you two kinds of rear parking sensors.
Invisible Parking Sensor

There are so many LED parking sensors, it is also called invisible parking sensor, the function is same with wireless parking sensor, but the difference is that, the LED screen of this parking sensor will only display the distance of the obstacles behind the car, and drivers can only see the data of the distance, but he can not know very clearly about what is it behind his car. Those kind of parking sensor can also propt via the warning beeper, so that driver can control whether he could remove his car or not.

Visible Parking Sensor

This kind of parking sensor usually consists: a rear view mirror monitor, back up camera, and the parking sensors. The buzzer alarm will prompt drivers if the obstacles are near their car. This senosr is more advanced than other kinds of parking sensors, as cameras will be installed in the rear bumper of the car, and take the pictures of the obstacles, then the rear view mirror monitor can display the image of what the obstacle is. So drivers can know the condition behind the car very well.

Wireless Parking Sensor

Wireless parking systems can come with four to eight sensors. All sensors are installed at the rear of the vehicle in 4 sensors system. Two sensors are installed at the front and four at the rear, this is 6 sensors System. If sensors are evenly divided between the front and rear bumpers of the vehicle, which is eight-sensor systems. The front sensors engage when the driver starts the car and the rear sensors activate when the driver goes in reverse.

Wireless parking sensor will prompt the driver when the driver approaches the obstacles through audible, visual or both means. Some systems will display the distance when the obstacle is within four feet from the front of the vehicle or six feet from the rear. Some systems will start to emit a warning beep"buzz" when there is some obstacles behind the vehicle's front or rear is under two feet. When the vehicle is within a foot of the other object, some systems send out a continuous tone to alert the driver and some models will display the word "Stop."
