What Does an Illuminance Sensor Sense?
An illuminance sensor, also known as a light sensor, detects and measures the intensity of visible light in an environment. It senses illuminance—expressed in lux (lx)—which quantifies how much luminous flux falls on a surface. This makes it essential for applications like automatic lighting systems, display brightness adjustment, and energy efficiency optimization.
Key Features and Applications
These sensors are widely used in smartphones, IoT devices, and smart buildings. They provide real-time data to adapt to changing light conditions, enhancing user experience and reducing power consumption.
Common Questions Answered
How accurate are illuminance sensors? Most modern sensors offer high precision, with some capable of measuring from 0 to over 100,000 lux. Can they detect different light types? Yes, many are designed to respond to both natural and artificial light sources.
