Sound Sensor

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), as well as recognize sound patterns and identify tone differences. 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) for use.
