Tips	Found in Logger Pro Data Collection Kit (demo 120 shelf 30) You will need the demo room laptop (in demo 120) or a personal computer with Logger Pro software installed. Ultrasonic pulses are emitted by the Motion Detector, reflected from a target, and then detected by the device. The time it takes for the reflected pulses to return is used to calculate position, velocity, and acceleration. This allows you to study the motion of objects. There is a sensitivity switch to choose between measuring everyday objects and motion on Pasco carts.
