Even VAZs, for example, VAZ 2110, can be equipped with such sensors.
Features of the rain sensors
When the wipers work when the first position is turned on, the rain sensor monitors the speed of the wipers. In this case, the intensity of glass cleaning depends on it. The more it rains, the more active the wipers will work. If the rain subsides, the wipers will slow down. As for position 2 and 3, in this case the wipers will work exclusively at a given speed.
It is important that the glass cleaning system can be controlled manually. So, for example, if the sensor is installed on the passenger side, then if the glass is dirty on the driver's side, the sensor may not recognize the pollution and will not turn on the wipers. Or it happens that in dry weather the sensor is triggered idle from the entry of beetles or leaves into the glass. In this regard, it must be possible to completely turn off the wipers or turn them on if necessary.
As an example for connection, the author proposed two rain sensors, one overseas production, and the second domestic.
Materials and tools for connecting:
- rain sensor of a suitable brand;
- glue;
- self-tapping screws;
- wires;
- a screwdriver, keys and other tools.
The process of connecting the rain sensor:
Step one. Installing an RS-22 Sensor
In total, the author considers two types of sensors, these are RS-22 of foreign manufacture, and also a DDA sensor of domestic manufacture.
How to install the sensor type RS-22:
1. The holder for the rain sensor must be glued to the windshield.
2. A special gel must be applied to the sensor housing, which will reduce the refractive index of the two working areas.
3. The base of the sensor housing is fixed to the base with a self-tapping screw.
4. At the final stage, we check that there are no bubbles between the working area of the sensor and the glass.
Step Two RS-22 Sensor Connection
Now you can start connecting the electrical part.The sensor is connected to the wiper mode switch.
1. The blue wire of the sensor is connected to the car body, this is a minus.
2. The red wire of the sensor must be connected to the pin with the designation "I", and the standard yellow wire with a green strip is turned off.
3. Now the yellow wire from the sensor needs to be connected to the yellow wire with a green strip.
4. And finally, the black wire is connected to the block, this is pin “53”, the blue wire is used for this.
In order for the device to start working correctly, first you need to calibrate it depending on the sensitivity and throughput of the glass. The sensitivity is adjusted so that the sensor is triggered at the desired degree of contamination or wet glass. You can learn more about how such a sensor works from its instructions.
Step Three Features of connecting the DDA sensor
The rain sensor of domestic production differs significantly from the sensor type RS-22. The most important thing that can be noted is the low cost of the sensor, ease of installation and the ability to connect without interfering with the main wiring of the car. Also, the system can be adjusted depending on how fast the car is traveling. The faster the car goes, the faster the wipers work, since the glass becomes dirty faster. Models of sensors type DDA-25 are installed on Kalina, as well as on Lada Priora. The difference between DDA-15 is only in the arrangement of contacts on the relay.
There is also a possibility to select a mode on the sensor; it can work to combat rain, snow, and also in standard mode.
How to install the DDA sensor
1. First, glue the sensor holder to the glass.
2. In the next step, you need to disassemble the vehicle mounting block and pull out the standard wiper control relay. Then, in its place, the DDA is simply installed.
3. On the front windshield rack on the left you will need to lay the wires.
4. At the final stage, it is necessary to adjust the sensitivity of the sensor.
You can learn more about how to connect the sensor in the video.
Conclusion
Of course, it is up to everyone to decide whether to install such a device on their car. But, of course, such an addition greatly simplifies and makes the process of driving a car more pleasant. Now the driver is more focused on the road, and this reduces the risk of accidents. Such a sensor costs about 1000 rubles, which is not so much.
You can also hear negative reviews about the rain sensor, some complain that it does not work on time or does not work as it should. But most likely, such motorists have a sensor installed without the ability to adjust the sensitivity, or they do not know how to use it.
