These devices primarily consist of a light signal emitter and a receiver: the emitter projects a beam of specific wavelengths, while the receiver captures the light. When a target object blocks or reflects the emitted light, it alters the light flux reaching the receiver. The receiver detects this optical variation and converts it into an electrical output signal. For light sources, such sensors typically utilize infrared or visible light spectra (red light for conventional detection, and green/blue light combinations for specialized color identification systems).
