Every year that passes technology seems to be getting better. We now have smart phones with facial recognition, smart TVs with motion sensors, smart homes you can communicate with, and even smart cars with rain sensing wipers. Now you are probably wondering how my windscreen knows when it’s raining, and you have probably been told that it’s just the sensors. But let’s get down to the science of it and find out how it works and how it will benefit you.
The science behind the magic
As you have probably already guessed it, yes the answer is sensors! But just how do these sensors operate? The rain sensors have the ability to be able to tell when it’s raining by measuring the amount of rain that gathers on your windscreen. The sensors work by sending out an infrared beam of light which detects how much light is reflected back through the glass. The more water on the glass the less light is reflected which in turn activates your wipers. This will also affect the frequency of wipers as the amount of rain changes. The sensors are usually located behind your rear view mirror mounted on a special bracket and wired through the roof.
How it makes your life easier
In extreme weather conditions you are already on the back foot; your vision and hearing is impaired as the rain thunders down on your vehicle, you’re concentrating on not hitting the car in front of you as you anxiously await their brake lights – the last thing we want to worry about is adjusting your wipers to the rain. It is all about the little things in life, if we can make our lives that one bit safer and easier, why wouldn’t we? From a drizzle to a down pour, rain sensing wipers are not just a luxury, they improve on our wellbeing and safety on the roads.
Depending on the extent of the damage to your windscreen, a closer inspection will be required to see if the rain sensor has been damaged. In most situations repairs can be completed easily without having to worry about the rain sensor as chips and cracks usually don’t affect the area. If a windscreen replacement is required then it is best to get the professionals to inspect your rain sensor as well, just inform the rep that you have a rain sensor mounted. If the sensor has been damaged then you may have to purchase a new one along with your windscreen replacement.
Some current brands of vehicles that offer this new technology are Ford and Hyundai, more specifically, the Kona which is an SUV from Hyundai as well as the Ford Ranger. It is always a good idea to ask your sales rep about this car feature to see if it can be added on.
