What Is a Light Sensor?
A light sensor, as its name suggests, is a mechanical or electronic apparatus that detects light. It is used to provide information on distance, shape, speed, dimensions, and even types of substances contained in a wide array of objects. Within industries ranging from architecture to offset printing, light sensors are essential tools used for their high level of precision. Often, they are also employed in day-to-day use by the layperson.

Within industries ranging from architecture to offset printing, light sensors are essential tools used for their high level of precision. Often, they are also employed in day-to-day use by the layperson. For example, every time a motion sensitive porch light or burglar alarm is activated, a light sensor has just been used. The way these products work is fairly straightforward. A light sensor inside the porch light or burglar alarm detects variance in its field of light sensitivity. Once the predetermined variance threshold has been reached, an electrical impulse is sent to activate the bulb or alarm.
