What Does an Illuminance Sensor Sense?
An illuminance sensor, also known as a light sensor, measures the intensity of visible light in an environment. It detects how bright or dim the surroundings are, providing data in lux units. These sensors are essential in automation systems, smart lighting, and energy-saving applications.
How It Works
Using photodiodes or phototransistors, the sensor converts light energy into electrical signals. This data helps adjust lighting dynamically, improving efficiency and user comfort.
Applications
Common uses include automatic brightness adjustment in smartphones, adaptive street lighting, and green building management. They enhance convenience while reducing energy consumption.
Frequently Asked Questions
Can it work in complete darkness? No, it requires some light to function accurately.
Is it the same as a motion sensor? No, motion sensors detect movement, while illuminance sensors focus solely on light levels.
