A light meter is a device used to measure the intensity of light in a given environment. It typically consists of a sensor that detects light, a display unit, and control buttons for operation. Light meters are commonly used in photography, cinematography, agriculture, construction, and environmental monitoring to ensure proper lighting conditions or to quantify light levels for various purposes.
