The digital EV3 Color Sensor distinguishes between eight different colors. 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….

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.

?Can also be used on Ev3?
Using the NXT brick, the Colour Sensor is able to perform three unique functions. It acts as a Colour Sensor distinguishing between six colours; it works as a Light Sensor detecting light intensities, both reflected light and ambient light; and it works as a Colour Lamp, emitting red, green or blue light. You will need a connector cable, which is included in the 9797 Base Set.

LEGO MINDSTORMS EV3 Gyro Sensor

The digital EV3 Gyro Sensor measures the robot’s rotational motion and changes in its orientation. Students can measure angles, create balancing robots and explore the technology that powers a variety of real-world tools

The digital EV3 Ultrasonic Sensor generates sound waves and reads their echoes to detect and measure distance from objects. It can also send single sound waves to work as sonar or listen for a sound wave that triggers the start of a program.

Expand your NXT experiences with the new NXT Compass Sensor and add accurate navigation to your Mindstorms® NXT projects. The NXT Compass Sensor is a digital compass that measures the earth’s magnetic field and outputs a value representing the current heading

The analog EV3 Touch Sensor is a simple but exceptionally precise tool that detects when its front button is pressed or released and is able to count single and multiple presses.

The temperature sensor is a digital sensor powered by the NXT brick. Using the NXT brick and NXT software 2000080, it can be calibrated to measure both Celsius and Fahrenheit (-20?C to 120?C/
