When I park my truck, I often look in the side and rearview mirror to make sure I’m not going to hit anything. If I’m not careful, I can back up too far or rub my tire against the curb. Now, many cars come with sensors or the option to install them later. I know this could be a lifesaver for me. <\/p>\n\n\n\n

Car parking sensors use ultrasonic sound waves or electromagnetic\u00a0fields to measure distance. They usually come with a visual display with audio sounds that indicate how close you are to objects. When you park, you will be able to tell how close things are to the bumper so you can avoid hitting them.<\/strong><\/p>\n\n\n\n

When signals reflect off objects and back to parking sensors, you can get a good idea if something is in your way most of the time. If you’re ready to stop bumping into objects as I do from time to time, then parking sensors might be a good investment. We’ll talk more about how sensors work and which ones you might want to choose for your vehicle. <\/p>\n\n\n\n

Types of Parking Sensor Systems<\/h2>\n\n\n\n

Ultrasonic and Electromagnetic<\/strong><\/p>\n\n\n\n

The two types of sensors you will find for cars are ultrasonic and electromagnetic<\/strong> sensors. If you have a car that has little round circles on your bumper, then I would first see if there are specific sensors for your car.<\/p>\n\n\n\n

These sensors send out unheard sound waves that can bounce off objects. Similar to sonar<\/strong>, sound signals are sent out and bounce back so the sensor can tell if something is there. The time it takes for the sound wave to come back to the sensor, lets the sensor system know how close an object is so it can show the driver. <\/p>\n\n\n\n

Some sensors work up to 30″ long and about 12″ wide. That’s why most sensors come in groups of four to give you a wider area of sensing what might be behind or in front of you.<\/p>\n\n\n\n

Know problems <\/strong>– These sensors aren’t great at distinguishing objects that are very thin in width or depth. The sound waves don’t bounce off of these objects well. In addition, they can usually only distinguish objects directly behind them and not higher or lower than the bumper. <\/p>\n\n\n\n
