data-collection parameters and use a wide variety of both Vernier and custom
sensors with the available channels and screw terminal.
Feedback and Control (Digital Out Lines)
Combining sensors with control via the SensorDAQ screw terminal or DIG channel
allows you to experiment with feedback. There are almost limitless possibilities
when using sensors to control output. This is the essential principle behind robotics.
In this example, we use a Vernier Stainless Steel Temperature Probe. As the data
rises to a preset threshold, a connected LED will light up. It will also help you
familiarize yourself with SensorDAQ's output lines.
1.
Open the example VI
“
ControlEx01_ControlDigOutWithSensor.vi” located in
Program Files\National Instruments\LabVIEW\user.lib\SensorDAQ\
EXAMPLES\Feedback and Control to start LabVIEW. The following VI will
appear along with instructions.
Digital out control with one Vernier analog sensor
2.
Connect a Stainless Steel Temperature Probe to Ch. 1. (The Voltage Probe
included with SensorDAQ could also be used in this example. Set the threshold
accordingly.)
