What Do Rain Sensors Do?
Rain sensors are part of automatic wiper systems. The rain sensor's job is to identify when there's water on the windshield.
Once water is detected, then the automatic wiper system turns on the wipers to keep the driver's view ahead as clear as possible in wet or rainy conditions.
What Are the Benefits of Automated Wiper Systems?
- Automatic wiper systems take the responsibility for turning wipers on away from the driver.
- This means the driver has one less task on their plate and can concentrate on driving. Automated wiper systems are especially helpful if the driver is tired or distracted by other occupants in the vehicle.
Where is the Rain Sensor on My Windshield?
If your vehicle has a rain sensor, it will normally be located near the rearview mirror:
Rain sensors have a strip of lens or film facing the outside of the windshield.
If your vehicle also has a light sensor for an automatic headlights system, then the light sensor will typically be next to the rain sensor.
How Do Windshield Rain Sensors Work?
Measure light to tell when it's raining
Windshield rain sensors measure the light reflected backwards by the windshield's glass to tell when it's wet or rainy. The more raindrops or water are on the windshield, the less light is reflected backward to the sensor.
Detect how much rain is on the windshield
By measuring the light reflected from the windshield glass, the rain sensor can not only tell when it's raining. It can also tell how much it's raining based on the amount of light it detects.
Set speed of the wipers according to amount of rain
When the sensor detects a certain amount of rain or water on the windshield, the automatic wiper system turns on the windshield wipers to the corresponding speed. If the wipers are already on, then it can also adjust the wiper speed to match the rain conditions if necessary.
