Adafruit 1356 TCS34725 FLORA Colour Sensor

The Adafruit FLORA Colour Sensor uses the TCS34725 sensor which includes 4 x photodiodes covered by an IR blocking filter for greater accuracy. Three of the photodiodes are covered with coloured filters to provide the individual RGB values and the fourth is left clear for an overall value. With a dynamic range of 3.8 million to 1 and adjustable integration time and gain it's even possible to use this sensor behind darkened glass or possibly fabric. Adafruit have added a neutral white LED to provide consistent illumination when you are trying to measure the colour of a surface. It is under software control so it can be switched off when not in use to save power or kept off depending on your application.

Adafruit have a free software library for you to download to get started.
