Table 1. WSN Node Specifications  
You can configure the four digital I/O channels for input, sinking output, or  
sourcing output. You must use an external power supply to provide sourcing  
output through the digital I/O channels, with a maximum total current output  
(aggregate on all channels) of 500 mA on the NI WSN-3212 and 1 A on the  
NI WSN-3202. The WSN-3202 also offers a 12 V, 20 mA sensor power output  
line that drives external sensors.  
Overview  
National Instruments wireless sensor networks (WSNs) deliver low-power  
measurement nodes that offer industrial certifications, reliable networking, and  
optional weatherproof outdoor enclosures for long-term, remote deployments.  
The measurement nodes have direct sensor connectivity and a 2.4 GHz radio  
to wirelessly transmit data to the WSN Ethernet gateway. Each measurement  
node offers four analog input channels and four digital I/O channels that you can  
configure for input, sinking output, or sourcing output. You can customize the  
behavior of programmable NI WSN measurement nodes with the NI LabVIEW  
Wireless Sensor Network (WSN) Module Pioneer. Use this module to perform  
custom analysis, embed decision making on NI WSN measurement nodes, and  
extend battery life by optimizing node behavior.  
Wireless Networking  
The measurement nodes and the NI WSN-9791 Ethernet gateway communicate  
wirelessly using 2.4 GHz radios and the reliable NI WSN protocol based on  
IEEE 802.15.4. The network accommodates up to 36 nodes per gateway and  
provides an outdoor range of up to 300 m with line of sight. The gateway  
maintains a list of nodes (by serial number) that have been authorized for  
network access. When a node powers up, it scans for available networks,  
locates either a gateway or mesh router node, and attempts to join. If the  
gateway has the node in its list, the node joins the network, downloads the  
latest configuration from the gateway, and begins its normal operation of  
Power  
You can power the NI WSN measurement nodes with four 1.5 V AA alkaline  
battery cells, with operation up to three years on battery power at one sample  
per minute, or with a 9 to 30 V supply of external power.  
acquiring measurement data and controlling digital I/O.  
Wireless Sensor Network Programmable Analog Input Measurement Nodes  
Mesh Networking  
Programming  
Gateways, routers, and end nodes work together to form a mesh network.  
You can integrate your NI WSN measurement data directly into the LabVIEW  
Measurement nodes can operate as routers or end nodes, providing the flexibility graphical development environment. After adding the WSN Ethernet gateway  
to extend the range of your sensor network. When nodes are configured as  
routers, they can repeat messages from end nodes and extend network range  
while acquiring measurement data. Router nodes must remain on to send and  
receive data across the network, and should be powered with an external source  
such as a 9 to 30 V supply, solar panel, or larger battery.  
to a LabVIEW project, the nodes configured with the gateway in MAX are  
automatically added underneath the gateway in the project, giving you instant  
access to their I/O and properties (see Figure 2).  
Software Overview  
With NI-WSN software, you can easily configure your sensor network in  
the NI Measurement & Automation Explorer (MAX) configuration utility  
(see Figure 1) and quickly extract measurement data from your wireless  
sensor network with the LabVIEW graphical development environment.  
Network Configuration  
MAX provides an intuitive user interface to add and remove measurement nodes  
and configure wireless settings. Upon connection, the WSN-9791 Ethernet  
gateway is autodetected under Remote Systems in MAX, and you can assign  
WSN nodes to the gateway by entering the node serial number. Upon power-up  
or reset, the nodes automatically connect to the assigned gateway. If a node is  
unable to connect, it executes a retry sequence with increasingly higher wait  
periods beginning with one minute between connect attempts and ending with  
55 minutes between connect attempts. This preserves battery power if a  
gateway is offline.  
MAX also provides an overview of the nodes connected to your network  
including their last communication time, battery status, and link quality. In  
addition, MAX offers an interface to set the wireless communication channel,  
configure the gateway IP address, and wirelessly update firmware on the  
measurement nodes.

Simply drag and drop I/O variables from a LabVIEW project to a LabVIEW  
block diagram for data extraction, analysis, and presentation (see Figure 3).

Wireless Sensor Network Programmable Analog Input Measurement Nodes  
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 Pioneer to scale and convert raw sensor data  
into meaningful engineering units before transmitting.  
With LabVIEW WSN Pioneer, you can also embed decision making 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.  
Figure 3. Extracting NI WSN Measurement Data Using LabVIEW  
Using the drag-and-drop LabVIEW variables, you can monitor the analog and  
digital channels as well as other node attributes such as link quality, battery  
voltage, and whether a node is configured as a router or end node. The LabVIEW  
Project interface also offers access to node property configuration utilities.  
You can modify node sample intervals, define the analog and digital channel  
parameters, and provide aliases.  
NI WSN Applications and Architectures  
With NI WSNs and access to the full breadth of NI platforms through LabVIEW,  
you have the flexibility to create simple, stand-alone wireless monitoring  
networks or completely integrated wired and wireless measurement solutions.  
In a simple architecture, as seen in Figure 4, the WSN measurement nodes  
acquire data and communicate wirelessly to the central gateway, which provides  
a wired Ethernet connection to a Windows or LabVIEW Real-Time host controller  
where you can log, analyze, process, and present your data.  
Node Programming  
You can customize the behavior of programmable NI WSN measurement nodes  
with LabVIEW WSN Pioneer. Use this module to perform custom analysis, embed  
decision making on NI WSN measurement nodes, and extend battery life by  
optimizing node behavior.  
With LabVIEW WSN Pioneer, you can significantly increase the battery life of  
your NI WSN measurement nodes while increasing performance and flexibility.  
By default, a node transmits every acquired value back to the gateway at the  
specified sample interval; however, 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 Pioneer,  
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.  
This also helps you achieve higher sample rates by customizing how the node  
acquires and transmits data. Exact sample rates depend on how many channels  
you are sampling, the analysis performed on each sample, and how many  
samples are transmitted back to the host. Without transmitting samples, the  
programmable WSN-3202 node can achieve a 35 Hz sample rate on one channel,  
while the programmable WSN-3212 can achieve a 4 Hz sample rate on one  
channel. Refer to the LabVIEW WSN Benchmarking white paper on NI Developer  
Zone for more information on increasing sample rates.  
Figure 4. NI WSN systems provide flexible connectivity to Windows or LabVIEW Real-Time  
host controllers.  
Furthermore, you can combine NI WSNs with other NI platforms to customize  
and enhance your measurement capabilities. You can complement your NI WSN  
with programmable automation controllers (PACs), vision systems, or even  
human machine interfaces (HMIs) to create a fully integrated solution that meets  
your unique application needs (see Figure 5).

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.
