The Complete Guide to Rain-Sensing Wipers: How They Really Work

Rain-sensing wipers use advanced infrared technology to automatically detect and respond to rainfall. Mounted behind the rear-view mirror, these smart sensors beam infrared light into the windscreen at a 45-degree angle. When raindrops hit the glass, they scatter this light, triggering photodiodes that measure the changes and adjust wiper speed accordingly. Beyond convenience, these systems enhance safety, reduce wear and tear, and even contribute to better fuel efficiency.
