Parking Sensors: How Do They Work & Why Should You Fit Them?

Parking sensors are probably something you’re already aware of, but you might not know exactly how they work and why you should add them to your vehicle.

Put simply, parking sensors use ultrasonic waves to judge distances, which is why they are sometimes referred to as ‘ultrasonic sensors’. They emit those waves and then receive them back off a nearby object. When your vehicle is in reverse, they will emit a tone that increases in frequency as you approach an object. When you start getting dangerously close to that object, the tone will become constant to let you know it’s time to reverse direction.

The most compelling benefits that come with parking sensors should be more than evident. They help you avoid accidents or damage when manoeuvring, and they take most of the stress out of reversing, particularly when you need to slip into tighter spots. Here are just a few more advantages that come with parking sensors.

Work at Night

Ultrasonic sensors work whether it’s the middle of the day or the dead of night. This makes them more useful than backup cameras, which are naturally a little limited when you’re reversing in the dark. Remember, it isn’t just when the sun goes down that this is useful – most parking garages are also on the darker side.

Automatic Operation

Whether it’s first thing in the morning or you’re just completing a few hours of driving, it can be easy to get complacent when reversing. Luckily enough, your parking sensors will never grow tired. They’ll be automatically activated as soon as your car enters reverse.

Easy to Fit

People tend to think that parking sensors are expensive to fit, or that they’ll made holes in the back of the vehicle. However, parking sensors are matched to your vehicle’s paint and are very unobtrusive. Better yet, they’re remarkably quick and easy to fit and don’t mark or damage the vehicle in the slightest.
