Motion Detector
 The Motion Detector uses ultrasound to measure distance. 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 such as a person walking, a ball in free fall or
a cart on a ramp.
Our Motion Detector can measure objects as close as 15 cm to the detector
and as far away as 6 m. The short minimum target distance allows objects to
get closer to the detector, which reduces stray reflections. A special Track
mode switch tailors the sensitivity for dynamics carts on tracks for lower
noise and higher quality data. The Motion Detector attaches easily to the
Vernier Dynamics System and has a pivoting head and rubber feet for ease of
use when not attached to a dynamics track. The cable is removable, so you
can use the Motion Detector with other interfaces with an alternate cable.
