How do the sensors work under the Star Wars universe. I was under the impression they are far less advanced than the Star Trek sensors. That is, outside the ship it can follow a craft, but inside the ship it's aware of life-forms but couldn't tell you exactly where they are.
I only think it is this way because the Falcon could easily track Tie-Fighters, but in Empire Strikes Back the sensors didn't go off for the Nynacks or whatever those things were chewing the power cables. Granted they were not inside the ship, but I often wonder if there is a difference in the Star Wars world when it comes to scanning a machine and scanning for life.
Thanks!
