I'm not sure if it has a sensor to tell or not, however it used to turn on right away as soon as I'd activated the spray on the rear window, however with the new wing and the stock lamp it sprays for a long period of time before it starts to actually activate the rear wiper. This seems to me to indicate that if the fluid isn't actually hitting the glass the wiper doesn't seem to turn on.
