Low-Power Wireless Measurement Nodes and NI LabVIEW Deliver Platform for Remote Monitoring Applications

Wed, 11/04/2009 - 9:17am
National Instrument's Wireless Sensor Network (WSN) platform is a complete remote monitoring solution that consists of NI LabVIEW graphical programming software and new reliable, low-power wireless measurement nodes.

The adoption of wireless technology for remote monitoring applications is growing, yet engineers and scientists struggle to find an integrated solution that can provide the required measurement quality, power management and reliable hardware for long-term, remote deployments.

The NI WSN platform takes advantage of more than 30 years of NI data acquisition system leadership to deliver an easy-to-use solution that provides high-quality measurement data, the flexibility to manage power consumption and the ability to customize wireless hardware for added functionality.

A key differentiator of the platform is LabVIEW software, which integrates seamlessly with the new battery-powered, industrial-rated NI WSN measurement nodes that can be deployed in rugged conditions for long periods of time.

Engineers and scientists worldwide are adopting wireless technology to meet distributed and portable measurement applications challenges, such as structural health and environmental monitoring, where wiring is difficult or cost-prohibitive.

With the flexibility of LabVIEW, the NI WSN platform simplifies and accelerates the development of these applications by delivering a drag-and-drop programming environment for configuring wireless systems, extracting measurements, performing analysis and presenting data. LabVIEW also offers native Web connectivity for remote interaction with wireless systems.

National Instruments is releasing its first two WSN nodes and plans to expand the measurement capabilities of the NI WSN platform. The wireless measurement nodes are powered by four AA batteries for up to three years, making them ideal for long-term deployments. The NI WSN-3202 four-channel, +/- 10 V analog input node and NI WSN-3212 four-channel, 24-bit thermocouple node have four digital I/O channels that can be configured for input, sinking output or sourcing output. The platform also includes the NI WSN-9791 Ethernet gateway, which is used to connect the measurement nodes to LabVIEW.
