Walking Motion Sensor

This experiment uses the computer and the multimedia system to display graphs of Distance vs Time, Velocity vs Time and Acceleration vs Time. An ultrasonic sound wave is emitted by a transciever and the signal bounces off of a moving object such as a person walking across the floor. The return signal is then timed and used to calculate the distance, velocity and acceleration based on the speed of sound.
