What Does an Illuminance Sensor Sense?
An illuminance sensor, also known as a light sensor, measures the intensity of visible light as perceived by the human eye. It quantifies illuminance in units such as lux or foot-candles, enabling precise environmental light monitoring.
Key Applications of Illuminance Sensors
These sensors are widely used in smart lighting systems, automotive displays, and consumer electronics to optimize brightness and save energy. They ensure ideal lighting conditions while enhancing user experience.
How Illuminance Sensors Work
Using photodiodes or phototransistors, the sensor converts light photons into electrical signals. Calibration against standard light sources ensures accuracy across various environments.
