Abstract: 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.
