Different Types of Light Sensors

Light falling on to the surface of a light sensor generates an electrical output proportional to the strength of the incident illumination. The sensor responds to a band of radiant energy existing within a narrow range of frequencies in the electromagnetic spectrum, which we characterize as light. These frequencies range from the infrared to the visible and continue to the ultraviolet region of the spectrum. Most light sensors are passive devices for converting the light energy of the spectrum Read more [...]
