Introduction
The Wireless Voltage Sensor is a combination wireless
and USB sensor that connects to a computer or tablet
device through , and can also connect to a
computer with a USB cable (included). The sensor
measures voltage in the range between -15 volts (V) and
+15 V. The sensor has built-in overload protection. The
PASCO Data Collection Software will display and ana-
lyze the measurements from the sensor. NOTE: The
software also supports “remote data logging” for long
term experiments.
The sensor is designed to optimize the battery usage
time. Since each sensor has a unique Device ID
number, more than one can be connected to a computer
or tablet at the same time.

from the Help menu, or press F1.
Compatibility
Check the PASCO Web page at
www.pasco.com/compatibility
for the latest information.
See Appendix A for more information about the PS-3500 Adapter and
Mac OS X models.
Initial Step: Charge the Battery
• Connect the Cable: Use the Micro USB Cable to
connect the micro USB port on the back end of the
Wireless Voltage Sensor to a USB port or USB
charger such as the PASCO PS-3501 USB
Charging Station. See the diagram.
• 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.
ON/OFF Information
To turn the sensor off, press and hold the ON button on
the back end of the sensor for a moment until the status
LEDs stop blinking. The Wireless Voltage Sensor puts
itself to sleep after several minutes of inactivity if not
connected and about one hour of inactivity if connected.

*Logging: PASCO wireless sensors can either stream
live data to a compatible device for “real-time” viewing or
log data (save it to the sensor’s memory). After logging,
the data can be uploaded to the computing device for
display and analysis at a later time. Logging capability
supports long-term or remote data collection while not
connected to a device.
Check the PASCO Web page at:
www.pasco.com/software
for the latest software version.
Set Up the Hardware
Connecting the Shrouded Test Leads to the
Sensor
• Connect the boot-shaped shrouded end of the red
test lead to the red voltage jack on the front end of
the sensor.
• Connect the end of the black test lead to the black
voltage jack on the sensor.
Connecting the Sensor for Measurement
Voltage is measured from one point to another point. For
example, voltage is measured “across” a component in a
circuit. The sensor is connected in parallel to the circuit;
not in series as a part of the circuit.
For example, in the diagram, the alligator clip of the red
test lead is connected to one end of a resistor that is in a
circuit with a battery. The alligator clip of the black test
lead is connected to the other end of the resistor. The
Wireless Voltage Sensor measures the “voltage drop”
across the resistor.
Set Up the Software
SPARKvue
Connecting the Wireless Sensor to a Tablet or a
Computer via Bluetooth
• For SPARKvue, select the Bluetooth icon to open
the Wireless Devices list. In the Wireless Devices
list, the sensors are ordered by proximity to the
device.
• Select the correct address that matches the
XXX-XXX number found on the sensor.

Troubleshooting the Wireless Voltage Sensor
• If the Wireless Voltage 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 turn it back on. Retry.
About the Battery
The Wireless Voltage Sensor’s battery is partially
charged at the factory. If the battery status LED blinks
red, use the included 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
to conserve battery life.
The battery life between charges for the sensor varies
depending on the sampling rate. The battery life ranges
between eleven 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
would be unusual. Even in the most extreme case with a
high sample rate, the Voltage Sensor battery would
support a full day of use before needing to recharge.
Maximizing Battery Life
One of the factors that affects battery life is the storage
temperature. Therefore, avoid storing the sensor in very
cold or very hot environments.
Suggested Experiments
Practically any experiment that uses a voltage
measurement can be done with the PS-3211 Wireless
Voltage Sensor. See the PASCO Web site at
www.pasco.com/products/lab-manuals

Appendix A: Compatibility
Check the PASCO Web page at
www.pasco.com/compatibility
for the latest information on Bluetooth SMART
compatibility.
*The PS-3500 USB Bluetooth 4.0
Adapter, when connected to a USB
port, allows up to three Bluetooth
SMART devices, such as this PASCO
wireless device, to connect to Windows
computers, Chromebooks, and older
Macintosh computers.
Note: The PS-3500 USB Bluetooth 4,0
Adapter is the only adapter we can currently
recommend. Many other Bluetooth 4.0 adapters are
available but this adapter has a specific design that
enables in-app pairing of Bluetooth SMART sensors.
1To check the Mac computer’s Bluetooth compatibility,
do the following:
• Click the  (Apple) Menu.
•Select
About This Mac
• Click the More Info ... button.
• Click the
System Report ... button.
•Select
Bluetooth from the sidebar on the left,
underneath
Hardware .
• Scan down the list of information until you find “LMP
Version”.
• If your Mac is equipped with Bluetooth SMART, the
LMP Version will show 0x6. (Anything lower than
0x6 means an older version of Bluetooth. Your
device will need the PS-3500 USB Bluetooth 4.0
Adapter.)
1The Mac Mini and MacBook Air were updated with
Bluetooth SMART support in 2011. The MacBook Pro
was updated in 2012. The Mac Pro that debuted in
December 2013 has Bluetooth SMART support.
Exception: Before you upgrade to El Capitan (Mac OS X
10.11.x), if you have a Macintosh with LMP version “0x4”
that requires the PS-3500 USB Bluetooth 4.0 Adapter,
please contact PASCO Technical Support for further
instructions.
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).
