To use this sensor and calculate Lux, there's a lot of very hairy and unpleasant math. [http://mchobby.be/PrestaShop/TSL2561.pdf You can check out the math in the datasheet] but really, its not intuitive or educational - its just how the sensor works. So we took care of all the icky math and wrapped it up into a nice Arduino library.
