Arduino Compatible Colour Sensor Module – RGB & Greyscale (3-Pin I/O)

You need to tell the difference between a red lolly and a green one, or sort components by colour in a line, and you don't want to wire up four separate photodiodes. This module reads individual red, green, blue, and greyscale levels through just three I/O pins. Built-in bright white LEDs give you even illumination so your readings aren't skewed by ambient light. There are mounting holes on the board, so you can bolt it into a project enclosure instead of hot-gluing it in. Three pins, four colour channels, done

• Reads individual red, green, blue, and greyscale levels
• Only 3 I/O pins required on your microcontroller
• Built-in bright white LEDs for even, consistent illumination
• Mounting holes for secure project enclosure installation
