What is a CMOS Sensor?

A CMOS sensor is an optical sensor that uses a group of Cadmium Magnesium Oxide Sensors to react to light energy by producing electrical signals. Sensors constructed in this way are used in may industrial applications as a method of electronically sensing or measuring light, or for electronically “photographing” a scene. In many cases, this technology is slightly more costly than CCD technology, but CMOS does have some technical features that can justify the added costs.
