This handheld device uses
several different sensors to measure and graph values on the
display. You can use it to experiment with how the various
sensors behave.
A sophisticated program
is included that has 9 different modes to measure various sensor
values over time. Several of the modes display a scrolling bar
graph that shows the relative value of the last reading as well
as the last 4 values before that. You can even adjust the
sampling rate (number of samples taken and plotted per second)
using the twist knob on the motor. See the programming
instructions for details on the various modes.
