It works by detecting infrared light that is emitted, reflected, and detected by the synchronous circuit. The intensity of the light is then utilized to determine if an item exists. It can easily distinguish between black and white lines. In other words, when a phototransistor passes through black and white lines, its different conduction levels might produce different output voltages. The value of all 8 outputs is used to determine the position of the tracking line.
