Wifi Revolution

National Instruments (News - Alert) said today that it’s extended the NI measurement hardware and software platform to wireless remote monitoring applications by launching 10 new WiFi (News - Alert) and Ethernet data acquisition devices, including built-in signal conditioning and direct sensor connectivity for electrical, physical, mechanical and acoustic signals.

 

The company said that by combining NI WiFi DAQ with the NI LabVIEW software platform, engineers and scientists can meet their wireless structural diagnostic, environmental and machine condition monitoring application needs by reducing cabling costs and increasing flexibility without compromising performance.

 

According to John Hanks, vice president of data acquisition and control at National Instruments, National Instruments data acquisition software for LabVIEW, ANSI C/C++ and Visual Basic .NET (News - Alert) is used to acquire data from millions of sensors all over the world. Thanks to NI WiFi DAQ hardware, developers can add wireless sensor capabilities to new and existing measurement applications without having to learn new software, according to the company.

 

NI says that the new NI WiFi DAQ devices uses the IEEE (News - Alert) 802.11 standard for wireless networks to stream data on each channel at more than 50 kS/s with 24 bits of resolution. This set of standards is developed by the IEEE LAN/MAN Standards Committee in the 5 GHz and 2.4 GHz public spectrum bands.

 

WiFi DAQ devices have the ability to deliver measurement data to a host PC instantaneously for real-time viewing and in-line analysis of dynamic sensor signals. The devices also has built-in advanced network authentication methods and 128-bit AES encryption, which offer network security and meet the standards defined for use of wireless networks in U.S. government facilities by the National Institute of Standards and Technology.

 

The company is shipping its WiFi and Ethernet DAQ devices with NI-DAQmx driver software and NI LabVIEW SignalExpress LE, an interactive data-logging software for quickly acquiring, analyzing and presenting data with no programming required. The NI-DAQmx driver can deliver time-saving features such as the configuration-based NI DAQ Assistant with code generation for both LabVIEW and text-based languages.
