Motion Sensor II
CI-6742A
Quick Start
1.
Connect the Motion Sensor II to your
ScienceWork-
shop
-compatible interface (such as the 850 Universal Inter-
face or
ScienceWorkshop
750 USB Interface).
2.
If you are using a computer, connect the PASCO interface to
it, turn the interface on, and start the data acquisition soft-
ware (such as PASCO Capstone).
3.
Place an object in front of the sensor at least 15 cm away.
4.
Click “Record” or press “Start” to begin recording data.
5.
Move the object in a straight line directly away from or
toward the sensor.
Introduction
The Motion Sensor II works with a
ScienceWorkshop-
compatible
interface and PASCO data acquisition software (such as PASCO
Capstone) to measure and record motion data. It produces a series
of ultrasonic pulses and detects the sound reflecting back from an
object in front of it. The interface measures the times between
outgoing pulses and returning echoes. From these measurements,
the data acquisition software determines the position, velocity,
and acceleration of the object.
This instruction sheet includes procedures for setting up the hard-
ware and software, collecting data, changing the sample rate,
mounting the sensor on equipment, and troubleshooting.
Theory of operation and specifications are listed at the end of the
instruction sheet.
Note: Essential PASCO Capstone tasks are described briefly in this
instruction sheet. For more instructions on using Capstone, see the User’s
Guide or the online help
