This app displays a graph of Luminosity (lux) vs. Time (s) that can be exported to Google Drive or in an e-mail as a .csv file (comma separated values).
Test the brightness/intensity of light sources using your phone light sensor. Use the light sensor to investigate the inverse-square law from a point source of light, true magnitudes of light bulbs (as our eyes do not directly perceive comparative brightness accurately due to the constriction and retraction of the pupil), solar intensity variations dependent upon weather, and the ability of objects and surfaces to absorb, reflect, and/or transmit light.
