myDAQ Hardware & LabVIEW Software together create a platform for showing students real world lab experience.

NI myDAQFor collecting and processing data

NI LabVIEWFor viewing and manipulating information.

Mini‐SystemFor sending project‐specific signals to and from myDAQ.

DAQ = Data Acquisition

DAQ is powerful, but was once too difficult or too expensive for education. Until myDAQ.

6

DAQ | dak |(short for data acquisition)The industry‐proven process of sampling real‐world physical conditions so the resulting values can be used on a computer.

Frequency

• How fast is the signal?• Measured in Hertz (Hz)

– number of signals per second

• Humans hear sound– 20Hz ‐ 20kHz

• CD Audio– 44.1kHz

• DVD Audio– XkHz

14

Amplitude

• How big/loud is the signal?

• Measured in Volts (V)– Often scaled or converted

• Two ended measurement

15

Analog vs. Digital

16

Analog Signals

• Measures 200,000 samples per second – 200 kHz

• Signal Range ‐10V to 10 V

• CD’s use 14 or 16 bit

Analog Exercise

• Use myDAQ and LabVIEW to read in an audio signal from a microphone

19

• Frequency – How often does the signal change

• Amplitude – How big is the signal

• Sampling Rate – How fast you read the signal– Samples per second, acquisition speed

• Resolution – How accurate you read the signal– Bit depth, accuracy, precision,

• Converters – Digital to Analog (DAC) / Analog to Digital (ADC)

ET1 I actually think we may not need this one. by the time I got to it in the presentation, I felt like I had already talked about it and was more saying "and this slide just reiterates that this is industry technology"Emily Thomson, 5/11/2011

Do‐it‐yourself‐ers. Go nuts.

myDAQ connects the PC to hundreds of sensorsand controls—from home‐made to high‐tech.

34

What will you connect?

myDAQ talks to sensors you already have,and plenty you haven’t tried yet.
