The other choices for Start or Stop Conditions are “Measurement Based” or “Time Based”.
A Measurement Based condition depends on the sensors
that are being used. For example, if the Smart Fan Acces
-
sory is attached to a Wireless Smart Cart, the Data Source
menu shows all the measurements possible with the Smart
Cart’s built-in sensors (for example, position and velocity).
Once a measurement is selected, the Start Condition win
-
dow changes to show “Condition” and “Value”.
The Condition choices are “Rises Above”, Falls
Below”, “Is Above” and “Is Below”. The “Value” text
box shows the unit of measurement (and because
Position is the selected measurement in this case, the
unit is “m” for meters). After the Condition is selected,
enter the value in the “Value” text box.
A Time Based condition controls the amount of time
that the computing device will “wait” before recording
data and the duration of the recording time. The Time
Delay minimum default value is 0.001 s and the Duration
minimum default value is 0.001 s. The Time Delay and
Duration do not have a maximum limit.
Measurement Based and Time Based conditions can be used together. For example, the Start Condition
could be a Time Delay, and the Stop Condition could be when the measured distance “Rises Above” a
certain value.
