Wireless Force-Acceleration Sensor (PS-3202)
Introduction
The Wireless Force-Acceleration 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
using the included USB cable. The sensor measures force up to
±50 newtons (N), acceleration up to ±16 g (where 1 g is equal to
9.8 m/s2), and angular rotation rate up to ±2000 degrees per
second (dps). The sensor measures force as a push or pull
along its x-axis and measures acceleration in three dimensions
(x, y, and z). PASCO Capstone or SPARKvue can show the
resultant acceleration. The sensor uses a micro-
electromechanical system (MEMS) device.
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.

Use this to mount the sensor to a rod or rod stand.
ON/OFF button
Press to turn the sensor on. Press and briefly hold to turn
the sensor off. Note that the sensor automatically turns
itself on when connected to a computer via USB. To
preserve battery, the sensor puts itself to sleep after several
minutes of inactivity if not connected.
Micro USB port
Use with the included micro USB cable 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.
Bumper attachment
Attach this to the threaded hole on the front of the sensor
when recording measurements from collisions or impacts.
Hook attachment
Attach this to the threaded hole on the front of the sensor
when recording measurements from forces pulling on the
sensor.
Cart/track thumbscrew
Use this to mount the sensor to a PASCO cart.
Micro USB cable (not pictured)
Initial step: Charge the battery
Charge the battery by connecting the micro USB port to any
standard USB charger. The Battery Status LED is solid yellow
while charging. When fully charged, the LED changes to solid
green.

Zero (tare) the sensor
At the beginning of an experiment, the measurement from the
sensor may not be zero when the force or acceleration is
actually zero. This is a normal behavior that is corrected when
you zero (or tare) the sensor using PASCO Capstone or
SPARKvue. For information on zeroing the sensor, check the
PASCO Capstone or SPARKvue online help and search for
"Zero sensor".
IMPORTANT: Zeroing of the acceleration
sensor should only be done if you are only
measuring the acceleration on a single axis, as
zeroing the acceleration sensor will cause the
other two acceleration measurements to no
longer be accurate.
Set up the hardware
Connecting bumper and hook attachments
Screw the bumper or hook attachment into the threaded hole on
the front end of the sensor, as shown below. This will connect
the attachment to the force sensor, allowing force values to be
properly recorded.
Direction of acceleration sensitivity
The acceleration sensing units inside the sensor are oriented so
that the lines of greatest sensitivity follow the x, y, and zarrows
indicating the direction of acceleration.
Figure 1. The axes of greatest acceleration sensitivity.
In the orientation shown in Figure 1, the x-axis direction is
'along' the axis of the sensor. The y-axis direction is
perpendicular to the axis of the sensor and parallel to the label
on top of the sensor. The z-axis direction is perpendicular to the
label on top of the sensor.
Calibration
The Wireless Force-Acceleration Sensor is calibrated at the
factory. Further calibration is not usually necessary, especially if
you are measuring a change in force, acceleration, or rotational
motion, rather than absolute values of any of these quantities.
However, it is possible to calibrate the sensor using PASCO
Capstone or SPARKvue. For information on this procedure, see
the Capstone or SPARKvue online help.
Mounting the sensor
Mounting the sensor on a rod
Slide the sensor onto a rod and secure it in place with the Rod
Clamp Thumbscrew, as shown below.
Mounting the sensor on a PASCO cart
1. Insert the included Cart/Track Thumbscrew through the
hole in the sensor labeled Cart.
2. Place the sensor onto the top surface of the PASCO cart.
Screw the thumbscrew into the threaded hole on the top of
the cart, securing the sensor in place.
Mounting the sensor on a Track Bracket
1. Mount the Force Sensor Track Bracket (ME-6622) into the
T-slot on a PASCO track.
2. Position the Wireless Force-Acceleration Sensor
underneath the Force Sensor Track Bracket, with the label
facing up. Ensure that the thumbscrew on the bracket is
directly over the hole in the sensor labeled IDS Bracket, as
shown in the figure on the next page.

3. Insert the thumbscrew into the hole labeled IDS Bracket.
Tighten the thumbscrew to secure the sensor in place.
About the battery
The Wireless Force-Acceleration 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
USB charger.
Maximizing battery life
Two factors that affect battery life are the storage temperature
and the number of charge cycles. Therefore, to maximize battery
life, avoid storing the sensor in very cold or very hot
environments, and disconnect the sensor from its charger once
it has been fully charged.
Troubleshooting
•If the Wireless Force-Acceleration Sensor loses Bluetooth
connection and will not reconnect, try cycling the ON
button. Press and briefly hold the button until the LEDs
blink in sequence, 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 persists, press and hold the ON
button for 10 seconds, then release the button and start the
sensor in the usual way.
•If the previous steps do not fix a connection problem, turn
Bluetooth off and then back on for your computer or tablet,
then retry.
