How Does the Automatic Rain-Sensing Wiper in Cars Work?

[VanVictoria]

The principle of the automatic rain-sensing wiper in cars is as follows: The specific area of the rain sensor is located at the bracket where the rearview mirror is attached to the windshield. The rain sensor is an optical system in the infrared band, with a light-emitting component responsible for emitting infrared rays. When the glass surface is dry, almost 100% of the light is reflected back, allowing the sensor to receive a significant amount of reflected light. The system then defaults to clear weather and does not activate the wiper. The automatic rain-sensing wiper detects the amount of rain and automatically adjusts its speed, eliminating the need for manual wiper adjustment. This removes the need for manual operation, ensuring the driver's clear visibility at all times, making trips safer and more comfortable, and enhancing both driving comfort and safety.
