optical sensor

Sees via photons

An optical sensor is a device that detects light and converts it into an electrical signal.

Optical sensors appear in cameras, motion detectors, barcode scanners, and fiber optic systems.

They may respond to visible light, infrared, or ultraviolet wavelengths: The optical sensor adjusts screen brightness based on ambient light.
