Capturing Data from Events

Although the StreamSmart 400 is capable of collecting data at high sampling
rates, as shown in Chapter 2, it is also versatile enough to gather data from
experiments of slower frequency—and even distinct events—with ease. You have
seen the power of streaming data in real time at speeds over 5,000 samples per
second with the streaming experiment. In this chapter, we go to the opposite
extreme to show you how simple it is to take a few isolated sample readings from
up to four sensors at a time and collect them into a data set for analysis. The
StreamSmart Aplet lets you capture data at any point in time and have the data
exported to corresponding rows of separate columns in the Statistics Aplet.
Additionally, you can have the readings auto-numbered in the order in which they
are collected, or you can add a numerical entry to each reading when it is taken.
Figure 3- 1 summarizes the steps involved in these types of experiments.
