3-Axis Acceleration/Altimeter Sensor

Introduction

•

Connect the sensor to a SPARKvue-compatible device 
and start the software. The sensor parameter screen 
opens and shows the list of measurements for the sensor.

•

In the sensor parameter screen, touch a measurement 
such as ‘Altitude’ to highlight it, and then touch ‘Show’ 
to open a graph display. 

•

Click “Record” or tap ‘Start’ to begin recording data.

The acceleration sensing units inside the sensor are oriented 
so that the lines of greatest sensitivity follow the three 
arrows indicating the direction of acceleration. 

In this orientation, the X-axis direction is ‘positive’ to the 
right, the Y-axis direction is ‘positive’ toward the end plate, 
and the Z-axis direction is ‘positive’ perpendicular to the 
label on top.

For example, if 
the sensor is on its 
side and oriented 
with its long axis 
horizontal as 
shown, the Accel-
eration X-axis 
reading is 1.0 g. If 
the sensor is ori-
ented with the 
X-axis arrow 
pointing down, 
the Acceleration 
X-axis reading is 
-1.0 g. 

If the sensor is ori-
ented with its the 
Y-axis arrow 
pointing up, the 
Acceleration 
Y-axis reading is 
1.0 g. If the sensor 
is oriented with the 
Y-axis pointing 
down, the Acceler-
ation Y-Axis read-
ing is -1.0 g. 

If the sensor is ori-
ented with the 
label facing up, the 
Acceleration 
Z-axis reading will 
read 1.0 g. If the 
label is facing 
down, the reading 
is -1.0 g.

The Acceleration Sensor can be set up so that it will auto-
matically zero itself when you start to record data. Or, the 
sensor could be mounted in the specific orientation needed 
for an experiment, and then set to zero from within the data 
acquisition software,
