I wonder how it works though, because Luke and Vader sense eachother only when they are close, not from afar. Unless, maybe one day Vader will show up on Tattoine.
i can see two possible explanations for this:
1. Vader lost a crapload of power when he lost his limbs, in the form of lost midichlorians. He might have lost some "finding" power, but Obi Wan may have not realized that and prefered to keep Luke safe.
2. Vader simply didn't have any reason to scan the galaxy for his son/daughter, not having known they were actually born. However Obi might've thought the day would eventually come when he WOULD find out somehow.
I'd prefer to go with the second one
