LEGO MINDSTORMS Education EV3 Color Sensor. Product Code: 730645

The digital LEGO MINDSTORMS Education EV3 Color Sensor with model number 45506 distinguishes between seven different colors and can also detect the absence of color. It also serves as a light sensor by detecting light intensities. Students can build color sorting and line-following robots, experiment with light reflection of different colors and gain experience with a technology that is widely used in industries such as recycling, agriculture, and packaging.

This EV3 color sensor provides the basis for discovering and understanding the implications of this technology in the industrial sector, where it can be used, for example, to automate a recycling line.

The color sensor has three different modes: Color, Reflected light Intensity and Ambient light intensity.

Colour – In this mode, the color sensor can differentiate up to seven different colors: black, blue, green, yellow, red, white, and brown. Each color is also represented by value (see “Colour and light data table” below). Note: For best results, the color sensor needs to be 1-2 cm away from the color you are trying to detect, and have consistent lighting.

Reflected light intensity – In this mode, the color sensor emits a red light and measures the amount reflected back into itself from the surface you are testing. The intensity of the light is measured as a percentage from 0 to 100, with 0 being very dark, and 100 being very bright.

Ambient light intensity – In this mode, the color sensor measures the amount of light in its environment, without producing its own light source. Ambient light intensity is measured as a percentage from 0 to 100, with 0 being very dark, and 100 being very bright.
