The gray scale sensor for arduino is a composition of a photocell (light-controlled variable resistor) and a integrated white LED on board aiming just front of the sensor. It's connected LED will let you compare and provide some reflective feedback to analyse gray scale light ranges. Different colors will apply but only gray scale values will be outputted. This new design includes a much better quality connector that increases life span of the sensor, better voltage range and easy to use.

• Wide voltage range from 3.3V to 5V
• Standard assembling struct (Times-of-5mm Center distance between two 3mm mounting holes)
• Icons to simple illustrate sensor function
• High quality connector
• Immersion gold surface
