This grayscale sensor can measure the intensity of light from black to white. A gray scale also known as black-and-white, is composed exclusively of shades of gray, varying from black at the weakest intensity to white at the strongest. The grayscale sensor for Arduino is a composition of a photocell (light-controlled variable resistor) and an integrated white LED on board aiming just in front of the sensor. 

Its connected LED will let you compare and provide some reflective feedback to analyze gray-scale light ranges. Different colors will apply but only grayscale values will be outputted. This new design includes a much better quality connector that increases life span of the sensor, and better voltage range, and is easy to use. 

This is a common sensor for automatic lamps that are turned on when light is not enough. For example, with a lack of sun the value will be low enough and this value can be used to trigger a relay to enable a lamp and shut down the lamp when the sunlight is back. Other light-sensitive devices could be used for simple data transmission, like Morse code with a flashlight. And can also be used as a line-following (tracking ) sensor.
