Where is the rain sensor located on the Haval H6?
2 Answers
The rain and light sensor of the Haval H6 is positioned at the center top of the front windshield inside the vehicle, near the interior rearview mirror. Classification of rain sensors: Rain sensors are suitable for meteorological stations, hydrological stations, agriculture, forestry, national defense, and other relevant departments to remotely measure liquid precipitation, precipitation intensity, and the start and end times of precipitation. They are used in hydrological automatic monitoring and reporting systems and automatic field monitoring stations for purposes such as flood control, water supply scheduling, and reservoir water management in power stations, serving as precipitation measurement sensors. Working principle of rain and light sensors: Currently, most rain sensors used in rain-sensing wipers are optical sensors. Optical sensors operate based on the principle of light refraction. Inside an optical sensor, there is a light-emitting diode that emits a conical beam of light, which passes through the front windshield. When there is no rain and the windshield is dry, almost all the light is reflected onto an optical sensor. When it rains, water accumulates on the windshield, causing some of the light to deviate. This results in a change in the total amount of light received by the sensor, thereby detecting the presence of rain.
I've driven a Haval H6 for several years, and the rain sensor is located beneath the rearview mirror bracket on the inner side of the front windshield. It looks like a small square box attached to the glass, designed to directly detect the size and density of raindrops falling on the windshield. During rainy days, this sensor automatically activates the wipers, saving me the hassle of manual control—a very user-friendly design. Once, when the wipers weren't responding well, I checked and found dust buildup on the sensor area, causing inaccurate detection. After cleaning, it worked normally again. When driving, it's important to keep the inner glass surface clean and avoid placing films or objects that could block the sensor, as this may affect performance. The sensor is fixed in that position for optimal rain detection visibility. If it malfunctions, don't attempt to force it open yourself—seek professional help, as it's close to internal circuits. Overall, knowing its location helps with regular maintenance and enhances driving safety in the rain.
