HiTechnic NXT Color Sensor V2

Call for price

Add a spectrum of color to your models with the new and updated HiTechnic Color Sensor (Version 2). Detect an extended range of more than 15 target colors and program your NXT robot to 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 new Version 2 Color Sensor has enhanced performance including better color recognition and longer detection range.

The new and totally redesigned HiTechnic Color Sensor Version 2 (V2) operates by using a single white LED (light emitting diode) to illuminate the target and analyses the color components of the light reflected by the target’s surface and calculates a Color Number that is returned to the NXT program.
