Thanks to the rapid development of technology, drivers can benefit from many amenities, such as a rain sensor in the car. This is an interesting addition that affects driving comfort and safety. You can find a new or used rain sensor for your car at Alpincars, as well as BMW car parts, including:
If we want the sensor to be matched to a specific make and model of the vehicle, it is worth using the part matching service by VIN. This allows you to maximize the potential of each add-on. What is a rain sensor in a car and why is it worth investing in?
A rain sensor in a car is an innovative element of car equipment that works well when driving in difficult conditions. During heavy rain, snow or hail, visibility is significantly reduced, which may result in dangerous situations on the road. Rain sensors in the car are hidden modules that are responsible for controlling the amount of water on the windows.
Rain sensor in a car - the principle of operation is relatively simple and does not require any reaction from us. After the first drops of rain appear on the windshield, the sensor sends a signal to the system and after about 0.1 s the wipers are turned on without our intervention. The sensor detects even very small amounts of water, but the microprocessor can be programmed to the intensity of rain at which we want the wipers to turn on.
The system uses LED diodes and the emission of infrared light that reacts to raindrops. During rainfall, light waves reflecting off the glass may have different intensity and the system adjusts the speed of the wipers so that the driver does not have to think about it. Therefore, when it is raining lightly, they work slowly, but they speed up when we overtake a truck or truck that splashes large amounts of water while driving.
Are you wondering how to install a rain sensor in your car and where it should be located? It is mounted on the windshield, near the rear-view mirror, and all the electronics are hidden in the headliner. The sensor itself is covered with gel to prevent it from getting dirty. In modern cars, it is part of the RLFS module, which also scans the environment in terms of temperature, humidity, lighting conditions and sunlight intensity.
A rain sensor in the car ensures greater driving comfort and safety, we do not have to waste time turning the wipers on/off and setting their speed. You can focus on the road conditions. What is especially important if we often drive on highways or expressways, where every second of the driver's reaction is important. However, it is worth turning it off in certain situations, for example when visiting a car wash, where the wipers could be damaged.
