An ambient light sensor is an environmental light detector. It is also known as an ALS or a photodetector. Numerous consumer devices and industrial applications frequently use this sensor. Their main roles include automatically adjusting the brightness of screens, controlling lighting systems, and executing a variety of tasks that depend on the prevailing lighting conditions around them. For instance, they are used in smartphones and laptops for screen brightness adjustment, in digital cameras for setting exposure levels, and in smart home systems for lighting control.

These sensors generally operate on the principles of photoconductivity or photodiode technology. They generate electrical signals proportional to the intensity of incident light, with changes in light levels resulting in variations in electrical resistance or current, thus measuring the light level. Ambient light sensors have a broad range of applications. In devices such as smartphones and laptops, they adjust screen brightness for optimal visibility and power conservation in different lighting conditions. They enhance energy efficiency in smart lighting systems by automatically dimming or turning off lights in response to natural daylight. Digital cameras use these sensors to set exposure times and apertures for properly exposed photos. In smart homes, they trigger actions such as adjusting blinds, turning on lights, or altering lighting color temperature based on the time of day and ambient light. In addition, in industrial settings, these sensors are employed for tasks such as quality control in manufacturing or sorting objects by color.
