Wireless 3-Axis Magnetic Field Sensor
(PS-3221)
Introduction
The Wireless 3-Axis Magnetic Field Sensor is a combination
wireless and USB sensor that connects to a computer or tablet
device through Bluetooth, and can also connect to a computer
with an included USB cable. The sensor measures the X, Y, and
Z components of the magnetic flux density in tesla, millitesla,
and gauss. The arrangement of the X, Y, and Z components is
shown on the top label.
The two magnetic field sensing elements are located in the end
of the probe. One sensing element is a three-axis ±50 gauss (G)
sensor located under the dot on the probe. The other sensing
element is a three-axis ±1300 G sensor located under the dot
surrounded by a ring. The bottom surface of the probe has
bumps at one centimeter intervals relative to the sensing
element location.
Equipment
Included equipment:
Wireless 3-Axis Magnetic Field Sensor
Sensor mounting rod
Micro USB cable (not pictured)
Features:
Sensing element indicators
Show the location of the sensing elements within the probe.
Probe
Contains the sensing elements used to measure magnetic
flux density.
Device ID
Use this to identify the sensor when connecting via
Bluetooth.
Bluetooth Status LED
Indicates the status of the sensor’s Bluetooth connection.

Logging data
For information on remote data logging, see the PASCO
Capstone or SPARKvue online help.
NOTE: The Bluetooth Status LED is disabled
when the sensor is connected to a computer via
the micro USB cable.
Battery Status LED
Indicates the battery level and charge status of the sensor.

ON/OFF button
Press to turn the sensor on. Press and hold to turn the
sensor off. To preserve battery, the sensor turns itself off
after several minutes of inactivity if not connected.
Micro USB port
Use with the included micro USB cable (not pictured) to
connect the sensor to a USB charger. The port and cable
can also be used to directly connect the sensor to a
computer without the use of Bluetooth. This connection
method is not supported by iOS.
Bumps at 1 cm intervals
Used to indicate distances.
Threaded hole (1/4-20)
Used to mount the sensor to the included mounting rod.
