The IR sensor consists of an individual IR LED and an IR Photodiode. The IR light emitted by the LED strikes the surface and is reflected back to the IR Photodiode. The photodiode then generate an output voltage proportional to the reflectance level of the surface (higher values for "light surfaces" and lower for "black/dark surfaces").
