(CI-6742A)
Features:
Range switch
Yellow plug (left)
Black plug (right)
Target indicator
Rotating head
Clips for mounting on track
Hole for mounting on rod
Ultrasonic transducer
Required equipment:
• ScienceWorkshop-compatible interface, such as the 550
Universal Interface (UI-5001)
• PASCO Capstone or SPARKvue data acquisition software
Quick start
1. Connect the Motion Sensor II to your ScienceWorkshop-
compatible interface, such as the 550 Universal Interface.
2. Connect the PASCO interface to the computer or tablet you
will be using, start the data acquisition software (PASCO
Capstone or SPARKvue), and connect the sensor to the
software.
3. Place an object in front of the sensor, at least 15 cm away.
4. Click Start
(SPARKvue) or Record
(Capstone) to
begin recording data.
5. Move the object in a straight line directly toward or away
from the sensor.
Introduction
The Motion Sensor II works with a ScienceWorkshop-compatible
interface and either PASCO Capstone or SPARKvue data
acquisition software to measure and record data. The sensor
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.
Get the software
You can use the sensor with SPARKvue or PASCO Capstone
software. If you’re not sure which to use, visit
pasco.com/products/guides/software-comparison
SPARKvue is available as a free app for Chromebook, iOS, and
Android devices. We offer a free trial of SPARKvue and
Capstone for Windows and Mac. To get the software, go to
or search for SPARKvue in your device’s
app store.
If you have installed the software previously, check that you have
the latest update:
SPARKvue
Go to Main Menu
> Check for Updates
PASCO Capstone
Go to Help > Check for Updates.
Set up the hardware
Connect the Motion Sensor II’s yellow plug to Digital Input 1 of
your ScienceWorkshop-compatible interface. Connect the black
plug to Digital Input 2.
NOTE: If you are using a PASPORT-only
interface, use a PS-2159 Digital Adapter to
connect the Motion Sensor II to the interface.
Connect the yellow plug to Input Port 1 and the
black plug to Input Port 2, then plug the Digital
Adapter into a port on the PASPORT-only
interface.
