The Arduino grayscale sensor is a combination of a photocell (light-controlled variable resistor) and an integrated white LED on the board, which is aligned directly in front of the sensor. The connected LED allows comparison and provides a reflective R&uum message to analyze the grayscale light areas. Different colors apply, but only grayscale values are output. This new design includes a much higher quality connector that extends sensor life, improves voltage range and simplifies operation.

This is a common sensor for automatic lamps that turn on when light is insufficient. For example, if the sunlight is absent, the value is low enough and this value can be used to trip a relay to activate a lamp and turn off the lamp when the sunlight returns. Other light-sensitive devices could be used for simple data transmission, such as Morse code with a flashlight. And can also be used as a line tracking sensor.
