A mobile application designed for devices utilizing the Android operating system, which measures illuminance. These applications employ the device’s built-in camera or light sensor to determine the intensity of light falling on a surface, displaying the results in lux or foot-candles. For instance, a photographer might use such an application to assess ambient lighting conditions before taking a picture.
This functionality provides a convenient and portable method for assessing environmental brightness. Historically, dedicated, often expensive, light meters were required for this purpose. The availability of the technology on a ubiquitous platform offers cost-effective and accessible means for tasks ranging from setting correct camera parameters to determining optimal lighting for workspaces or horticultural environments.
