Add a spectrum of color to your models with the HiTechnic Color Sensor. Detect a range of target colors and program your NXT robot react to each color. Build a color sorter to sort LEGO bricks or a line follower that will detect different color lines and surface colors.

The HiTechnic Color Sensor is “tuned” to standard LEGO colors. When positioned over a surface, the Color Sensor will return a numeric value identifying the target color.

The NXT Color Sensor operates by using three different color light emitting diodes (LED) to illuminate the target surface and measures the intensity of each color reflected by the surface. Using the relative intensity of each color reflection, the color sensor calculates a Color Number that is returned to the NXT program.

The Color Sensor connects to an NXT sensor port using a standard NXT wire and uses the digital I2C communications protocol. The Color Number calculated by the sensor is refreshed approximately 100 times per second.

The Color Sensor is housed in a standard Mindstorms sensor housing to match the other Mindstorms elements.

To test your new sensor, plug it into port 2 of your NXT and select View > Ultrasonic cm > Port 2. Position the sensor approximately 1/4" (6mm) from a colored surface. A Color Number in the range of 0 - 17 will be displayed. As you move the sensor over different colored surfaces, the readings will change. (0 will display as ?????? while in View mode.)
