Modern Robotics Color Sensor

• Color sensor to detect the color of a target
• Typical Maximum Range: 7 cm
• Power: 5 VDC 20mA max / 4 pin I2C port
• Operational Frequency: 50Hz or 60Hz

The Modern Robotics Color Sensor detects the color of a target and returns values identifying the color. The Color Sensor operates in two modes, Active and Passive. The mode can be selected by writing the required mode code to the Command register. 

In Active mode, the internal LED provides the light source for detecting the target color. Best results in Active mode are obtained when the target is within about 7cm of the color sensor. In Passive mode, the internal LED is switched off and the sensor detects the color of the light from an external light source such as a colored LED or lighted device.
