Abstract
A sensor assembly comprises a housing having a major face and a side edge. The side edge is formed of a material that is capable of conducting light. A photosensitive element is positioned within the housing and facing the major face of the housing. A reflector is positioned within the housing. The reflector is shaped to direct light entering through the side edge onto the photosensitive element.
Claims1
A controller for use in a load control system for controlling an electrical load, the controller comprising:
- a processor configured to:
- combine a first sensor signal and a second sensor signal from at least a first sensor assembly and a second sensor assembly, respectively, the first and second sensor signals representing light levels at a window, the first and second sensor assemblies oriented so that the first sensor assembly has a maximum response to light entering a housing of the first sensor assembly at a first angle with respect to a normal of a plane of the window and the second sensor assembly has a maximum response to light entering a housing of the second sensor assembly at a second angle with respect to the normal of the plane of the window;
- and
- transmit a command to automatically control the electrical load based on the combined first and second sensor signals.
