Has anyone retro-fitted a rain sensor to their car before?? And if so how easy/hard is it to do?

Technical Rain sensor...
not going to be an easy one need a new windscreen for a start (the sensor is in the screen) before you get to the electrical side of it buy some Rain-X or Aquapel if your too lazy to turn the wipers on

This looks too cheap to be any good, unless??

Mine came with 2 as standard, they are on my face. They sense rain hitting the screen and send a signal to my brain to send a signal to my hand to turn the wipers on.
:d:d:d
I will try to install it this week if I have time. Then I will tell you if it works or not

You don't need to buy a new windscreen, just buy the sensor itself and then connect it to the A-Bus(Another kind of communication protocol just for the sensor) on the Body Computer, then, enable the sensor using MultiECUScan and make a Proxy Alignment. Take a look at GP eLearn
Take a look what I've done with MultiECUScan:
Now I'm waiting for the sensor [emoji16]

I bought only the sensor without buying a new windscreen. Take a look:

Hello Bernie,
yes, the rain sensor can be enabled at Proxy Alignment settings, you have to enable it, and them make proxy aligment. And on eLearn, it says that low speed is auto mode, and the others are for changing the speed. And if the sensor is broken, it will works like at car LOW-ended version (without rain sensor).
If you don't have the sensor, after proxy alignment, on your menu (on car cluster), it will show a new option (rain sensor) that is for setting sensibility of the sensor. On MES you will see that again, on Proxy Alignment, that still is not present. That is due to during alignment, the car check where nodes (modules and so on) are connected, and if it does not detect the sensor at "A-BUS" on the body computer (yes, there is a conection BUS just for rain sensor, from the sensor to body computer directly), it will not finish properly the alignment, and it shows an error while performing alignment, but on cluster will recognize it successfuly.
On eLearn there is not too much info about how it works, but I hope that I can get it work. I just need to add to wires on two connectors on the body computer, one for voltage, and other for A-BUS. GND is connected directly to car chassis.
That is similar like when I enabled the cruise control. First times that I tryed without turning on the switch, and after 3 or 4 months I was like crazy trying to find out what happens with this damn module, and this is the answer. Also, the air intake sensor was damaged
On a Spanish Fiat forum, there is another guy asking the same, and all the people says the same as here (it is impossible...you have to buy a new windscreen...you are a lazy guy...) and I am informing on both sites, here and on the Spanish forum.
If I get the sensor working, I will make a manual. Promised
Best regards,
Julio.
Here it is! Take a look at the attachments. As you can see, the Arduino's wires fit like charm at sensor pins
Best regards,
Julio.

Hi Julio
How did it go? Did you fit the sensor to the car?
I believe you need a silicon gel pad in between windscreen and the sensor
Thanks

Hi BobLeeSwagger,
The sensor is not installed yet.
That is true. You'll need the gel pad. You can found it on eBay for about 14-15 Euros.
Now I have some free time due to holydays, I will try it then.
Regards,
Julio.

Nice
I was just wondering if we can use a different model rain sensor. found same 3 pin rain sensor from a fiat stilo for cheap.
after all its the same signal sending to the body computer right?

Pls send me a link or photos of the sensor, I need the sensor S/N or ID.

Unfortunately, my body computer doesn't want to enable rain sensor option. When I enable it and then I do the proxy aligment, the body computer reports a fail at some point "Fail-Procedure Out of range, but, on the other hand, the dashboard recognizes the option and it enables on menu the rain sensor sensibility option. Once it has finished the proxy alignment, I go back to the enable/disable options menu on MultiECUScan 3.0 and it keeps disabled (Rain sensor and also I tried with dusk sensor). I also tested with AlfaOBD (PC and Android version) and it says "Fail sub parameter blablablah....".
I don't know if the body computer needs to be a different module or software since it doesn't leave me to, for example, enable "Comfort close/opening" and use the remote to open and close windows. Maybe replacing the body computer might fix that issue, but It will cost a bunch of $$ even if the body computer is from 2nd hand due to we need to reprogram inmo and key decoder, replace the chip from the new body and then use my old chip, or clone info to new chip (2nd and 3rd options are quite dangerous if you do it wrong)
I will keep trying, but for now is not possible. I can also try to use a MCU to emulate the ECU system and turn the windshield washers on

I think I found the issue, the car body computer knows that my car is a Dynamic Version, and it might be the issue, because my car does not has Rain sensor by default, but the instrument cluster let me do it because is a newer version from another GP Sport or Emotion, wich it includes Rain Sensor. On the other hand, I think I has not sense, because my car, as Wikipedia says: "Dynamic version does not come with Cruise Control or Front Fog lights, but I was able to install them, so I think that my problem come from the OBDII adapter, and I think I will have to buy another more advanced than my Chinese ELM327 WiFi heheheUnfortunately, my body computer doesn't want to enable rain sensor option. When I enable it and then I do the proxy aligment, the body computer reports a fail at some point "Fail-Procedure Out of range, but, on the other hand, the dashboard recognizes the option and it enables on menu the rain sensor sensibility option.

If I have time, I will buy a better OBDII adapter and try it again.

*Pls read the previous message, there is some interesting info*
The sensor that it will work with your car is the Opel/Vauxhall, it is the same as GP hehehe.
I recommend to test the sensor before try to install it on car. It works with 12v power supply. Use a 12v and apply power and then check between +12v and GND goes almost +12v, and between GND and Signal there are some voltage.
Rain sensor's pinout on eLearn is "K085" and electronic diagram and how windshield wipers work are described at "E3020"
Pin 1(RED): +12v goes to Body computer - Connector E - PIN 7
Pin 2(BLACK): GND goes to Chassis GND
Pin 3(GREEN): Signal +12v goes to Body computer - Connector A - PIN 35
Regards,
Julio.
