Your robot's "ears!

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.
