A programmable photoelectric sensor and a system for programming/controlling the photoelectric sensor and for monitoring the performance of the photoelectric sensor. The system includes a processor coupled to the photoelectric sensor, which is operative for generating at least one graphical user interface and for programming/adjusting the operation of the photoelectric sensor; and a display device coupled to the processor for displaying the graphical user interface. The processor programs/adjusts the operation of the photoelectric sensor in accordance with selections of an operator utilizing icons displayed on the graphical user interface.

Programmable photoelectric sensor and a system for adjusting the performance characteristics of the sensor

A photoelectric sensing circuit for adjusting the hysteresis of a photosensor. The photoelectric sensing circuit includes a photosensor capable of receiving light and generating an output signal indicating the amount of light incident on said photosensor. The photosensor generates a first output signal when the level of received light is above a first predetermined level, and a second output signal when the level of received light is below a second predetermined level. The circuit further includes a variable light source for generating and emitting the light incident on the photosensor and a power source coupled to the light source. The power source has a variable output level for controlling the intensity of the light emitted by the light source. Finally, the photoelectric sensing circuit also includes a control circuit coupled to the variable power source for varying the output level of the power source. In accordance with the operation of the photoelectric sensing circuit if the photosensor is outputting the first output signal, the control circuit reduces the output level of the power source so that the intensity of the emitted light results in a level of received light received by the photosensor which is below the first predetermined level, and if the photosensor is outputting the second output signal, the control circuit increases the output level of the power source so that the intensity of the emitted light results in a level of received light received by the photosensor which is above the second predetermined level.
