The motion sensor and control side of the relay should be on one source. The load side of the relay and fluorescent should be from a second source. (Both hot and neutral)
Those outdoor sensors are not real sensitive to movement towards them, so if you come into the shop and start working, without playing with the switch, your lights may go out on you.
If it was my place, I'd install a second switch location and wire it up as a 3-way. Then I'd yell at anyone that forgot to turn the lights out. (Right there, before you went out the door.)
