and embed local decision making on NI WSN measurement nodes.
With the LabVIEW WSN Module, you can significantly increase the battery life of your NI WSN measurement nodes while increasing performance and flexibility. Instead of
transmitting every received string or value back to the gateway, in many applications it is sufficient to simply monitor a given input for a threshold crossing or average values over
a period of time. In these applications, powering the radio to transmit every acquired sample uses excessive power and reduces battery life. With LabVIEW WSN, you can add
intelligence to the node to transmit data only when required. Additionally, you can monitor battery voltage and network status as well as modify the sample interval of the node to
optimize behavior for specific operating conditions.
Using a subset of LabVIEW analysis functions and floating-point math operations, you can preprocess data acquired by NI WSN measurement nodes. A variety of analog and
digital sensors can interface directly with these nodes, and you can use LabVIEW WSN to scale and convert raw sensor data into meaningful engineering units before
transmitting.
With LabVIEW WSN, you can also embed intelligence on NI WSN measurement nodes, so decisions can be made autonomously without transmitting the stimulus and response
to and from a host computer or embedded controller. You can use the digital output lines on an NI WSN measurement node to actuate relays and perform simple on/off control.
For example, a programmed node can turn on a fan when a temperature threshold is exceeded, which reduces response time and increases reliability by removing the need for
host interaction.
NI WSN Applications and Architectures
NI wireless sensor networks are ideally suited for long-term remote monitoring applications such as environmental monitoring, water quality monitoring, structural health
monitoring, energy quality and consumption monitoring, transportation, and machine condition monitoring. NI WSN measurement nodes can withstand outdoor and industrial
environments and reliably monitor assets or surroundings to provide enhanced visibility into the overall health of your systems or processes.
The NI WSN platform can function as a simple, stand-alone wireless monitoring system, or be combined with other hardware components to achieve a complete wired and
wireless measurement and control system. Through LabVIEW, you can combine NI WSN devices with other NI platforms to customize and enhance your measurement
capabilities. You can complement your NI WSN with embedded NI CompactRIO systems, vision systems, or even human machine interfaces (HMIs) to create a fully integrated
solution that meets the unique needs of your application.

Accessories
NI WSN accessories include options for gateway and measurement node mounting as well as weatherproof enclosures for outdoor use of the measurement nodes and gateways.
Available mounting accessories include options to panel mount and DIN-rail mount WSN measurement nodes and gateways. The NI WSN-3281 magnetic panel mount kit
provides easy setup and takedown on virtually any metal surface. For high shock and vibration applications, NI recommends a panel mounting configuration rather than DIN rail.
The NI WSN-3291 is an outdoor weatherproof enclosure for NI WSN measurement nodes. The enclosure features two I/O glands for routing power or sensor cables and is
shipped with four I/O gland inserts and two I/O gland plugs so you can customize the glands for your application. The WSN-3291 offers an IP65 (Ingress Protection) rating to
protect NI WSN measurement nodes for long-term, outdoor deployment.
Please view the WSN accessories data sheet for a complete list of WSN mounting accessories, outdoor enclosures, backshell kits, and power supplies.

Support and Services
System Assurance Programs
NI system assurance programs are designed to make it even easier for you to own an NI system. These programs include configuration and deployment services for your NI PXI,
CompactRIO, or Compact FieldPoint system. The NI Basic System Assurance Program provides a simple integration test and ensures that your system is delivered completely
assembled in one box. When you configure your system with the NI Standard System Assurance Program, you can select from available NI system driver sets and application
development environments to create customized, reorderable software configurations. Your system arrives fully assembled and tested in one box with your software preinstalled.
When you order your system with the standard program, you also receive system-specific documentation including a bill of materials, an integration test report, a recommended
maintenance plan, and frequently asked question documents. Finally, the standard program reduces the total cost of owning an NI system by providing three years of warranty
coverage and calibration service. Use the online product advisors at ni.com/advisor to find a system assurance program to meet your needs.
