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 software (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 hardware and software, collecting data, changing the sample rate,
mounting the sensor on equipment, and troubleshooting.

Set-up
To Connect to a PASCO Interface
Connect the Motion Sensor's yellow plug to DIGITAL INPUT 1
(or Digital Channel 1) of your ScienceWorkshop-compatible
interface. Connect the black plug to DIGITAL INPUT 2 (or Digital Channel 2).
NOTE: If you are using a PASPORT-only interface (such as the
SPARK Science Learning System), use a PS-2159 Digital
Adapter to connect the Motion Sensor to the interface. Put the
yellow plug into Input Port 1, and the black plug into Input Port
2. Plug the Digital Adapter into a port on the PASPORT-only
interface.
PASCO Capstone Setup
6. Confirm that the “Hardware Setup” panel shows the icon of
the Motion Sensor and the icon of the interface.
7. Double-click the Graph icon in the Displays palette (or
other display icon) to create a data display.
8. In a Graph display, click the “Select Measurement” menu
button on the vertical axis and select position, velocity, or
acceleration. Click “OK”.
SPARK Science Learning System (SLS) Setup
1. Turn on the interface. Connect the Motion Sensor’s plugs to
the input ports on a PS-2159 Digital Adapter, and plug the
adapter into the interface.
1. Turn on the interface and launch the PASCO data acquisition
software, such as PASCO Capstone..
2. In PASCO Capstone, click the “Hardware Setup” icon in
the Tools palette to open the “Hardware Setup” panel.
3. In the “Hardware Setup” panel, click “Add Sensor/Instrument” to open the “Add Sensor or Instrument” window.
4. In the “Add Sensor or Instrument window, click the “Sensor
or Instrument Type” menu and select “ScienceWorkshop
Digital Sensors” from the list.
5. Select “Motion Sensor II” in the list and then click “OK”.
2. The SPARKvue program recognizes that the Digital Adapter
is connected to the interface, and shows a screen with a list
of digital sensors. Press “Motion Sensor” and then press
“OK”.
