Adafruit RGB Colour Sensor with IR filter
• RGB and Clear light sensing elements• IR blocking filter, integrated on-chip and localised to the colour sensing photodiodes allows for more accurate measurements• 3,800,000:1 dynamic range with adjustable time and gain so suitable for use behind darkened glass• 3.3V regulator so you can power with 3-5VDC safely• Level shifting for i2c pins means you can use 3.3V or 5V logic• Neutral 4150K temperature LED with MOSFET driver onboard to illuminate what you'r trying to sense (can be turned on or off using any logic level output• 20.44mm by 20.28mmYour electronics can now see in dazzling colour with this lovely colour light sensor. We found the best colour sensor on the market, the TCS34725, which has RGB and Clear light sensing elements. An IR blocking filter, integrated on-chip and localized to the colour sensing photodiodes, minimizes the IR spectral component of the incoming light and allows colour measurements to be made accurately. The filter means you'll get much truer colour than most sensors, since humans don't see IR. The sensor also has an incredible 3,800,000:1 dynamic range with adjustable integration time and gain so it is suited for use behind darkened glass.
We add supporting circuitry as well, such as a 3.3V regulator so you can power the breakout with 3-5VDC safely and level shifting for the I2C pins so they can be used with 3.3V or 5V logic. Finally, we specified a nice neutral 4150°K temperature LED with a MOSFET driver onboard to illuminate what you're trying to sense. The LED can be easily turned on or off by any logic level output.
Connect to any microcontroller with I2C and our example code will quickly get you going with 4 channel readings. We include some example code to detect light lux and temperature that we snagged from the eval board software.

Wire up the sensor by connecting VDD to 3-5VDC, Ground to common ground, SCL to I2C Clock and SDA to I2C Data on your Arduino. Restart the IDE and select the example sketch and start putting all your favourite fruit next to the sensor element!
