A lux sensor works by detecting the intensity of light in its environment and converting it into an electrical signal, which can then be measured. It typically uses a photodiode or phototransistor to sense light levels and outputs a voltage or current proportional to the light intensity, often calibrated to measure in lux, the unit of illuminance. This allows the sensor to provide information on how bright or dim the surrounding area is, which can be used in various applications like automatic lighting controls and display brightness adjustments.
