Introduction
The PS-3223 Wireless 3-Axis Acceleration/Altimeter
sensor measures acceleration in three axes, angular
velocity in three axes, and altitude. The sensor can be
mounted to any PASCO cart using the included
thumbscrew. The included hook and loop strap can be
used to mount the sensor to a variety of objects. For
additional mounting options, the sensor casing includes a
threaded hole that accepts 6-32 screws, such as the
PASCO Truss Set Screws.

Data collection tips
Acceleration
Acceleration is measured using an electronic three-axis
accelerometer. Due to the way an accelerometer
functions, the acceleration measurement will be offset by
9.8 m/s
2
in the direction normal (perpendicular) to the
surface of Earth. For example, if the x-axis of the sensor
is normal to Earth’s surface, this axis will measure
9.8 m/s
2
when at rest. If the sensor is rotated so that the
y-axis is normal to Earth’s surface, the y-axis will now
measure 9.8 m/s

(Figure 1).
