National Instruments myDAQ

USER GUIDE
NI myDAQ
NI myDAQ is a low-cost portable data acquisition (DAQ) device that uses NI LabVIEW-based
software instruments, allowing students to measure and analyze real-world signals. NI myDAQ
is ideal for exploring electronics and taking sensor measurements. Combined with NI LabVIEW
on the PC, students can analyze and process acquired signals and control simple processes
anytime, anywhere.
