Physics Toolbox Light Sensor

Physics Toolbox Light Sensor


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.

See a review of this app in the Institute of Physics' physics education periodical: "Map and apps widen the scope of school physics." Physics Education. (May 2013). pg. 409-410. Retrieved online at: http://goo.gl/YtVfXe

Very good app! Don't listen to the person who said it only has 2 values, it works perfectly, this person was probably testing it with a flashlight in a dark room or something.. Also, the developer tells me that he is working on an RGB version. If you like this app then try out the Physics Toolbox Suite (by the same developer) to take advantage of all of the sensors on your device! It includes this app and many more all in one package that is still free, still has no ads, and still uses minimal permissions (so it's non-invasive).
