What is DAQ?
Data acquisition (DAQ) is the process of measuring an electrical or physical phenomenon, such as voltage, current, temperature, pressure, or sound. A DAQ system consists of sensors, DAQ measurement hardware, and a computer with programmable software.

SYSTEMS
DAQ System Options
NI offers PC-based systems with plug-and-play DAQ devices with fixed functionality or configurable systems that let you mix and match hardware.
PC-Based Systems
Achieve electrical and physical measurements with a customizable, accurate, yet cost-effective way to conduct benchtop measurements.
CompactDAQ
This portable, flexible approach is ideal for applications with a wide mix of measurement types, where scalability and flexibility are important. Hardware ruggedness makes it a great fit for high-channel-count distributed applications in the field.
CompactRIO
Take advantage of real-time data processing capabilities, sensor-specific conditioned I/O, and a closely integrated software toolchain for long-running, industrial data acquisition applications.
PXI
Use this modular approach for high-channel-count data acquisition and sensor measurement applications. Systems range from tens to hundreds of channels, mixing and matching measurement functionality and output capabilities.
Find the Right DAQ Hardware
NI’s DAQ devices are divided into categories to help you easily find options that meet your needs. Select by measurement type, such as temperature or strain, or common form factors, including USB.
