How to tell if car has rain sensor?
In order to detect whether your car has a rain sensor or not, you can pay attention the next time it rains and see if the wipers are getting switched on automatically or not. Rain sensor gel pads need to be replaced each time we perform a windshield replacement. If you’re not sure if your vehicle is equipped with a rain sensor, look at the photos below and if you still aren’t sure, just give us a call and we’ll help you. If all you need is a windshield repair from a stone chip or some other object making contact with your windshield, you will not need a new rain sensor gel pad.
What is a rain sensor?
There are many different techniques that automakers have experimented with to eliminate or substitute the wiper system. A rain sensor is a fairly recent addition to the windshield of a car. The technology has been around since the 50’s, however, rain sensors didn’t become prevalent in cars until the late 1990’s. Today, they are fairly common in domestic and foreign passenger vehicles and trucks. A rain sensor detects the presence of water on the glass of the windshield. The sensor then prompts the car to turn on the wipers automatically whenever rain is detected.
How does a rain sensor work?
The rain sensor works on the principle of total internal reflection. This technique makes use of infrared radiation. An infrared light beams at a 45-degree angle on a clear area of the windshield from the sensor inside the car. When it rains, the wet glass causes the light to scatter and lesser amount of light gets reflected back to the sensor.
Why does my car's windshield wiper work when it rains?
When it rains, the wet glass causes the light to scatter and lesser amount of light gets reflected back to the sensor. When the amount of light reflected back reduces to a level preset by the software inside the sensor, it automatically switches on the wiping mechanism of the car to start the drying process.
How does the software determine the speed of the wipers?
The software also determines the speed of the wipers depending on the amount of moisture accumulation. This speed changes according to the detection of moisture by the sensor.
Do you need a rain sensor pad for a windshield?

Where is the rain sensor located on a car?
Initially integrated in the mirror base of the rear-view mirror, the rain sensor is fitted on the inside of the front windshield outside the driver's field of vision. Within the sensor area, the sensor detects when it is raining and transmits its information to the windshield wiper's control electronics. The wiper frequency in the intermittent wiper setting can therefore be automatically adapted to the intensity of the rain. Thus, manual intervention by the driver is now more or less unnecessary.
How does a rain sensor work?
The sensor element comprises one or more light emitting diodes (transmitters), a prism and a photodiode (receiver). A light beam produced by the light emitting diode passes via a prism to the windshield, is reflected several times by the outer windshield surface and forwarded to the photodiode.
What is solar sensor?
The solar sensor records the insolation through the windshield affecting the driver and passenger and transmits this value to the air conditioning control unit. The information is evaluated in the control unit and used to control the air conditioning in the vehicle interior. The spatial sensing area of the solar sensor corresponds roughly to a hemisphere, which is tilted forwards by the inclination of the windshield.
How is the illuminance of a vehicle recorded?
The illuminance around the vehicle is recorded using the ambient light sensor over a large spatial angle ( Figure 6 ).
What is a special algorithm for a vehicle sensor?
A special algorithm uses the sensor data and by including further information from the vehicle electronics detects various lighting conditions (day, night, dusk or passing through a tunnel/bridge) and switches the daytime running light on or off accordingly.
How is external lighting measured?
The external lighting conditions are measured by an optoelectronic detector. Using an upstream filter glass, the sensor records special wavelengths in order to distinguish between artificial light and daylight. The ambient light and front-end lighting are measured by two sensors, which function independently of one another.
How do raindrops affect the reflection properties of a windshield?
Raindrops on the windshield change the reflection properties to the extent that all light beams no longer reach their target and are deflected by the drops of water ( Figure 5 ). The greater the intensity of the rain, the less light reaches the photodiode.
How to check if you have a rain sensor?
You can check if you have a rain sensor system in your car. First, if your wipers automatically turn on when raindrops come in contact with the windshield then you have a sensor. You can also check by looking from the outside – behind the rear view mirror.
Where is the rain sensor on a car?
The rain sensor can be found behind the rear view mirror. Some are found on the wipers. The technology uses optical detection or sensing, analog signal processing and a control algorithm during operation or when the rain or snow hits the windshield. When there is an interruption to the infrared system (i.e.
How to tell if windshield has rain sensor?
One way is to look at your windshield from outside the vehicle around were the rear view mirror is mounted. If you see a round or rectangular gel pad stuck to the inside of the glass than that is the rain sensor pad.
Why do we need rain sensors?
