THIS THING CHANGED MY LIFE!!! NOW I CAN SEE ALL COLORS, JUST WITH THIS SENSOR!! IT IS AWESOME. I THINK I AM IN LOVE WITH THIS PRODUCT.
This product has been discontinued. The new version of this sensor can be found here.
This Color Sensor also has a built-in IR (optical) and Proximity Sensor and white LED for active target lighting. Supports High Speed I2C Communication (400kHz) as well as auto increment register read which allows the user to return all the color register and status register data in one read command instead of 4 separate read commands.
