ABSTRACT:
A sensor system to turn on room lights when a person enters such room but avoids nuisance tripping of the system when a person passes near but outside of the region to be monitored. The inclusion of blinder devices which can be individually set, ahead of the sensor elements, permit the region being monitored to be tailored to the particular room or location. Adjusting levers can be used to set the positions of the blinder devices and then covered to prevent tampering with the settings of the blinder devices. Special fasteners can be used to limit access to the adjusting levers.
