The DAQiFi Nyquist 1 is a self-contained, mobile connected, battery powered, wireless data acquisition device. It’s perfect for general data acquisition applications where economical, feature-rich DAQs are required.

Nyquist is completely wireless, utilizing a built-in Li-Ion battery for power and an 802.11 WiFi connection, allowing it to be deployed virtually anywhere and everywhere. Since it uses the 802.11 standard, it can be used on the Wi-Fi network already implemented in many facilities. Open source hardware and software allow the DAQiFi Nyquist to be adapted to any data acquisition application. Drivers and APIs are available to interface with 3rd party software such as NI LabVIEW or Wolfram Mathematica.

One of the most exciting aspects of the Nyquist is that it eliminates the need for a dedicated PC plugged into each data acquisition solution. Because the Nyquist connects wirelessly, many devices can be deployed and are able to connect to the same client. PCs, experiments, machines, robots, etc. can all be connected to one client at once.

Why Nyquist is Better

Data acquisition is commonplace in most engineering, scientific, and academic environments. However, most of these systems have limited capability or high cost. They generally require separate software purchases and dedicated computers to collect data. Many data acquisition systems still require the user to learn proprietary programming languages.

After extensive experience in engineering/scientific environments at universities and engineering companies, the founders of DAQiFi observed most users were spending excessive time configuring and programming their data acquisition devices. This detracted from their main goal: collect and analyze data essential to the task at hand.

The founders of DAQiFi envisioned a better solution: modular, portable data acquisition with flexible wireless connectivity. The features in the new Nyquist line of data acquisition devices were intended to provide anyone with the ability to easily collect the data they need without wasting time learning the intricacies of data collection setup and software.

Did you know? The DAQiFi Nyquist has been tested as a beta product on numerous projects, including a 0g test-flight for portable fire extinguishers headed to the International Space Station.

Can it do more?

For power users, the device is capable of interfacing directly with industry standard software such as National Instruments’ LabVIEW and Wolfram’s Mathematica. DAQiFi’s line of products are not only capable of data acquisition - they can be controlled using the free, bundled software, the aforementioned third-party software, as well as operate as dedicated dataloggers (SD card required). Future product development and updates will allow these products to be programmed like a PLC or other microcontroller and operate autonomously according to the user’s programming.

Aside from ease-of-use and rich feature-set, the DAQiFi hardware is designed to be incredibly robust. All of the ports and electrical interfaces are protected against overvoltage, overcurrent, electrostatic discharge, and reverse polarity. The USB interface and internal lithium ion battery are protected with automatically resetting polyfuses and are safeguarded against overvoltage, overcurrent, improper charging, and temperature extremes.

Excellent for Everyone from Education to Business

K-12 Education Educators can use these devices in their classrooms as demonstration tools or hands-on devices.

University Research Undergraduate and graduate engineering students use these devices everyday in their schoolwork/research. Often, these students spend far too much time setting up, programming, and troubleshooting their data acquisition systems which detracts from the actual science they are trying to conduct. This valuable time could be reallocated, making research more efficient from both time and budget standpoints.

Engineering Research and Development Engineering companies can utilize the Nyquist as a tool for collecting data during the research and development phases of their business. Software libraries are available to program custom solutions for customers’ products for a complete, professional data acquisition and control solutions.

Small Business Small businesses could embed these devices into quality control machinery, medical devices, or use them to tune the suspension on a race car - to name a few examples.

Hobbyists The Nyquist can be paired with an Arduino or Raspberry Pi to serve as a powerful hardware interface for either of these microcontrollers and single board computers. You can use the Nyquist to make custom projects like robots, interactive arcade games, WiFi controlled RC cars, etc.
