In modern cars, various components and systems come together to create a perfect experience. From essential components like brakes and engine to safety features like child-locks and cruise control, everything contributes to the experience. The rain sensor windshield is one such innovation to improve the driving experience in rainy weather. Although the rain sensor windshield dates back to the 1950’s, it has become more common in latest vehicle models. <\/p>\n\n\n\n

Different types of automotive glasses<\/a> protect you from dust, rain, and UV rays. Moreover, this rain sensor on car windshields<\/a> helps the driver with proper visibility during rain by automatically switching on the wipers. Here’s a guide on how a windshield rain sensor works, its installation and benefits.<\/p>\n\n\n\n

WHAT IS A WINDSHIELD RAIN SENSOR?<\/strong><\/h2>\n\n\n\n
\"what
The rain sensor detects the light dispersion and sends signal to turn on the wipers automatically<\/figcaption><\/figure>\n\n\n\n

The windshield rain sensor works on a simple phenomenon. When the rain droplets fall on the windscreen, the sensor detects the water presence and switches on the wipers automatically. The sensor mounts on the rear-view mirror in the car cabin and makes contact with the windscreen.<\/p>\n\n\n\n

WORKING OF RAIN SENSOR IN THE WINDSHIELD<\/h2>\n\n\n\n

The rain sensor basically detects the light rays. When the rain drops fall on the windshield, the sensor detects the shattering of the infrared light rays in different angles. In this way, the rain sensor sends the signal to the car computer<\/a> which automatically operates the car windshield wiper blades<\/a>.<\/p>\n\n\n\n

HOW TO USE WINDSHIELD RAIN SENSOR?<\/strong><\/h2>\n\n\n\n
\"How
Turn the stalk to auto to make use of automatic windshield rain sensor and also, set the sensitivity of wiper blades<\/figcaption><\/figure>\n\n\n\n

The windshield rain sensor functions fine, that is if it rains, the wipers automatically start functioning. In some circumstances when the wiper knob, button or stalk is not switched to auto mode, you will have to operate it manually. <\/p>\n\n\n\n

You can simply switch on the auto mode and drive comfortably in the rain. In auto mode, you can change the sensitivity or speed of the wipers according to your requirement. For instance, in light rain, you can keep the sensitivity low. <\/p>\n\n\n\n

In other conditions, if the wipers are not working, you can replace them with new ones to drive safely in rainy, foggy or misty weather. The windshield rain sensor may also malfunction or not work. Therefore, it’s better to get it replaced by an auto service technician. <\/p>\n\n\n\n
