Your robot's "ears!"
See More Features
Using the NXT Brick (sold separately), the Sound Sensor allows your LEGO® MINDSTORMS® NXT robot to hear! The Sound Sensor is able to measure noise levels in both dB (decibels) and dBA (frequencies around 3–6 kHz where the human ear is most sensitive).
- Includes 1 Sound Sensor.
- Does not include connector cable.
- This is the individual component, and does not include the NXT Intelligent Brick, software or any accessories. It requires the complete LEGO MINDSTORMS NXT set (#8527 or #8547) for use.
