Introduction
The Wireless Current 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 current in two ranges: between -1 ampere (A)
and +1 A, and between - 0.1 A and + 0.1 A. The PASCO
Data Collection Software will display and analyze 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.

Software Help
See the SPARKvue Help or PASCO Capstone Help for
information about collecting, displaying, and analyzing
data.
• In SPARKvue, select the HELP button in any screen
including the Home Screen.
• In PASCO Capstone, select PASCO Capstone Help
from the Help menu, or press F1.
Compatibility
Check the PASCO Web page at
www.pasco.com/compatibility
• Connect the Cable: Use the Micro USB Cable to
connect the micro USB port on the back end of the
Wireless Current 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 Current 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.
The Wireless Current Sensor has built-in protection
against damaging over-current. If the current exceeds
±2 amps, the sensor will make a sonic alarm and the
status LEDs will both shine red.
If this happens, take the steps necessary to reduce or
stop the current through the sensor. For example, disconnect the power source. Analyze the circuit to determine why the over-current happened, and don’t
reconnect the power source until the problem is fixed.

About the Battery
The Wireless Current 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
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 Current 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 Current
measurement can be done with the PS-3212 Wireless
Current Sensor. See the PASCO Web site at
Troubleshooting the Wireless Current Sensor
• If the Wireless Current Sensor loses Bluetooth
connection and will not reconnect, try cycling the ON
button. Press and briefly hold the button until the

port, allows up to three Bluetooth
SMART devices, such as this PASCO
wireless device, to connect to Windows
computers, Chromebooks, and older
Macintosh computers.

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).
