Claim 6:
7. A method of orienting a photocontrol for a lighting fixture, the method comprising:
receiving, from a first photosensor, a first data signal indicating a first ambient light level at a first section of the photocontrol;
receiving, from a second photosensor, a second data signal indicating a second ambient light level at a second section of the photocontrol, wherein the first section and the second section of the photocontrol receive various ambient light levels at various periods of a diurnal cycle;
determining, at a first time period of the diurnal cycle, a first instant ambient light differential between a first light level detected via the first photosensor and a second light level detected via the second photosensor;
determining, at a second time period of the diurnal cycle, a second instant ambient light differential between a third light level detected via the first photosensor and a fourth light level detected via the second photosensor;
calculating, based on the first instant ambient light differential and the second instant ambient light differential, a temporal ambient light differential between the first section of the photocontrol and the second section of the photocontrol, the temporal ambient light differential being between the first time period and second time period of the diurnal cycle;
determining, based on the temporal ambient light differential, a variation of the ambient light levels detected via the first photosensor and the second photosensor between the first and second time periods of the diurnal cycle;
identifying, based on the variation of the ambient light levels, a triggering photosensor of the photocontrol, wherein the triggering photosensor is identified as at least one of the first photosensor or the second photosensor; and
modifying, based on a further data signal indicating a further ambient light level detected via the triggering photosensor, an output level of a lighting element included in the lighting fixture.
