Direction of Acceleration Sensitivity
The acceleration sensing unit inside the Smart Cart is
oriented so that the lines of greatest sensitivity follow the
three X-Y-Z arrows indicating the direction of
acceleration.
In this orientation, the X-axis direction is ‘along’ the long
axis of the Smart Cart, the Y-axis direction is
‘perpendicular’ relative to the top of the Smart Cart. The
Z-axis direction is ‘perpendicular’ to the long axis of the
Smart Cart and parallel relative to the top of the cart.
Test the Smart Cart’s Output Using Earth’s Gravity
Start the PASCO Data Collection Software. If the Smart
Cart is held so that the X-axis on the top of the Smart
Cart is vertical and pointing upward, the Acceleration
X-axis reading is +1.0 g. If the Smart Cart is turned so
the X-axis is vertical but pointing downward, the
Acceleration X-axis reading is -1.0 g (where “g”
represents the acceleration due to gravity).
If the Smart Cart is held so that the accessory tray is on
top and horizontal, the Acceleration Y-axis reading is 1.0
g. If the Smart Cart is turned so that the accessory tray is
horizontal and on the bottom, the Acceleration Y-Axis
reading is -1.0 g.
If the Smart Cart is placed so its side so that the Z-axis
on the top of the cart is pointing upward, the
Acceleration Z-axis reading is 1.0 g. If the Smart Cart is
placed on its other side so the Z-axis is pointing down
-
ward, the Acceleration Z-axis reading is -1.0 g.
