The I2C Color Sensor from Seeed Studio offers a whopping 8*2 array of filtered photodiodes to achieve great color detection. The 16 photodiodes include 4 red filters, 4 green filters, 4 blue filters and 4 have no filter.

This sensor is designed to work with Grove shields and uses I2C to communicate with your microcontroller.

Features:

• Grove compatible
• 16-bit digital output with I2C at 400 kHz
• Operating temperature of  -40°C to 85°C
• Programmable interrupt function with User-Defined Upper and lower threshold settings
