Introduction
The Wireless Motion Sensor is a combination wireless and
USB sensor that connects to a computer or a tablet device

through Bluetooth, and can also connect to a computer with
a USB cable (included). The sensor measures distances to
an object from 15 centimeters to 4 meters. The sensing
element can be rotated 180 degrees. The sensor can be
mounted on the end of any PASCO track or on a support
rod up to 12.5 millimeters in diameter. Use the Cart Adapter
Accessory to mount the sensor on any PASCO Dynamics
Cart. (See “Equipment Mounting”.)
How It Works
An electrostatic transducer in the face of the Wireless
Motion Sensor transmits a burst of sixteen ultrasonic
pulses with a frequency of about 49 kHz. This burst of
pulses can be heard as a single click. The ultrasonic pulses
reflect off the target and return to the face of the sensor.
Sound intensity decreases with distance; to compensate,
the sensor increases the gain of the receiver amplifier as it
waits for the echo. The increased gain allows the sensor to
detect an object up to 4 m away. The lower gain at the
beginning of the cycle reduces the circuit's sensitivity to
echoes from false targets
The sensor measures the time between the outgoing
pulses and the returning echoes. It uses this time and the
speed of sound to calculate the distance to the target. To
determine velocity, the software uses consecutive position
measurements to calculate the rate of change of position.
Similarly, the software determines acceleration by using
consecutive velocity measurements.

Initial Step: Charge the Battery
• Connect the Cable: Use the Micro USB Cable to
connect the micro USB port on the end of the sensor to
a USB port or USB charger such as the PASCO
PS-2575 USB Single Port Charger. Charging begins
automatically. The charger circuit inside the sensor
turns itself off when the unit is fully charged. The
battery status LED will shine yellow as the battery is
charging, and will shine green when the battery is
charged. The battery is partially charged at the factory.
Initial charging time may be three hours or longer
depending on the power source and the condition of
the battery.

Set Up the Software
SPARKvue
Connecting the Sensor to a Tablet or a Computer via Bluetooth
• For SPARKvue, select the Bluetooth icon. In the
Wireless Devices list. The sensors are ordered by
proximity to the device. Select the correct address that
matches the Device ID XXX-XXX number found on the
sensor. Select Done.
Connecting the Sensor to a Computer with the Micro USB Cable
• Connect the micro end of the included Micro USB
Cable into the micro USB port on the end of the sensor.
Connect the other end of the Micro USB Cable to a
USB port on the computer, or into a powered USB hub
connected to the computer.
• In the SPARKvue Home Screen, select a measurement
from the list under the sensor’s name. A graph of the
measurement versus time opens.
Green blink Connected Green ON Charged
Yellow blink Logging*
*Logging: PASCO wireless sensors can either stream live
data to a compatible device or log data (save it to the
sensor’s memory). The data can then be uploaded to the
device for display and analysis at a later time. Logging
capability supports long-term or remote data collection
while not connected to the device.
Note: The latest versions of SPARKvue and PASCO
Capstone support logging. Check the PASCO Web page
at:
www.pasco.com/software
for the latest software version.
ON/OFF Information
To turn the sensor on, press the ON button. The status
LEDs will blink. To turn the sensor off, press and hold the
ON button for a moment until the status LEDs stop blinking.
The sensor puts itself to sleep after 1 hour of inactivity if
connected, and after several minutes if not connected.
Collecting Data
• Select the Start button to begin collecting data.
PASCO Capstone
Connecting the Sensor to a Tablet or a Computer via Bluetooth
• For PASCO Capstone, select Hardware Setup in the
Tools palette. In Hardware Setup the sensors are
ordered by proximity to the device. Select the address
that matches the Device ID XXX-XXX number on the
sensor.
Select a display in the main window or from the Display
palette. In the display, use the <Select Measurement>
menu to pick a measurement to be shown.
Connecting the Sensor to a Computer with the Micro USB Cable
• Connect the micro end of the included Micro USB
Cable into the micro USB port on the end of the sensor.
Connect the other end of the Micro USB Cable to a
USB port on the computer, or into a powered USB hub
connected to the computer.
• In PASCO Capstone, select a display in the main
013-15991A
window or from the Displays palette. In the display,
use the <Select Measurement> menus to pick the

Collecting Data
• Select Record to begin recording data.
Troubleshooting the Sensor
• If the sensor loses Bluetooth connection and will not
reconnect, try cycling the ON button. Press and briefly
hold the button until the status LEDs blink in
sequence, and then release the button. Start the
sensor in the usual way.
• If the sensor stops communicating with the computer
software or tablet application, try restarting the
software or application. If the problem remains, press
and hold the ON button for 10 seconds and then
release. Start the sensor in the usual way.
• Turn Bluetooth off and then back on. Retry.
Equipment Mounting
Mount the Wireless Motion Sensor as illustrated on a
vertical rod (a) or a horizontal rod (b).
The sensor can “see through” a wire screen or rubber band
placed close to the transducer.
Integrated clips on the lower front end of the sensor allow it
to be attached to the end of a PASCO track (c).
A threaded hole in the bottom of the unit (d) is provided for
attachment to the Motion Sensor Bracket (e), the Cart
Adapter Accessory (f), and other 1/4-20 threaded mounting
devices such as a camera tripod.
To protect the Wireless Motion Sensor from being hit by an
object, use a device such as the Motion Sensor Guard (g)
or Photogate Brackets with a rubber band (h).
About the Battery
The sensor’s battery is partially charged at the factory. If
the battery status LED blinks red, use the micro USB cable
to connect the sensor to a USB port or a USB charger.
Battery Usage
Battery life is very important to making the sensor simple
and always ready to use, so all of the PASCO wireless
products are designed for long battery life. For example,
the sensor turns itself off after a few minutes of inactivity.
The battery life between charges for the sensor varies
depending on the sampling rate. The battery life ranges
between 11 hours for high sample rates to more than 70
hours for low sample rates.
In typical classroom/lab use, this would translate to a
battery life between charges ranging from one to four
weeks or more, because full-day continuous sampling
4
013-15991A
Technical Support PS-3219
would be unusual. Even in the most extreme case with a
high sample rate, the sensor battery would support a full
day of use before needing to recharge.
Maximizing Battery Life
One factor that affects battery life is the storage
temperature and the number of charge cycles. Therefore,
avoid storing the sensor in very cold or very hot
environments.

What is Bluetooth SMART
®
?
Bluetooth SMART (also known as Bluetooth Low Energy or
Version 4.0 of the Bluetooth specification) is the latest
protocol of the proprietary open wireless technology
standard created by telecoms vendor Ericsson in 1994. It is
the power- and application-friendly version of Bluetooth
that was built for the Internet of Things (IoT).
