What Does an Illuminance Sensor Sense?
An illuminance sensor, also known as a light sensor, is a device that measures the intensity of visible light. It detects the amount of light falling on a surface, typically measured in lux or foot-candles. These sensors are widely used in applications ranging from smartphone displays to smart lighting systems.
Core Functionality and Applications
Illuminance sensors work by converting light energy into an electrical signal. They are essential in automation, helping adjust screen brightness or control indoor lighting based on ambient conditions. If you’re curious to learn more, what does a illuminance sensor sense in practical scenarios? It senses environmental light to optimize energy efficiency and user comfort.
