What Does an Illuminance Sensor Sense? A Comprehensive Guide

An illuminance sensor is a device that measures the intensity of visible light as perceived by the human eye. It senses illuminance, which is the amount of light falling on a surface, typically measured in lux (lx) or foot-candles (fc). These sensors are essential in applications like smart lighting, photography, and energy management systems.

Key Functions and Applications

Illuminance sensors detect ambient light levels and convert them into electrical signals. They are widely used in automatic lighting control, display brightness adjustment for devices, and environmental monitoring.
