Table 1. WSN Node Specifications
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
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
to wirelessly transmit data to the WSN Ethernet gateway. Each measurement

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.
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.
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
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

to extend the range of your sensor network. When nodes are configured as
to a LabVIEW project, the nodes configured with the gateway in MAX are
routers, they can repeat messages from end nodes and extend network range

access to their I/O and properties (see Figure 2).
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.
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.

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

Using the drag-and-drop LabVIEW variables, you can monitor the analog and

need for host interaction.
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.
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
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.
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).

Accessories
NI WSN accessories feature options for gateway and measurement node
mounting as well as a weatherproof enclosure for outdoor use of the
measurement nodes. 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.
