Wireless Sensor Network Programmable Analog Input Measurement Nodes
Mesh Networking
Gateways, routers, and end nodes work together to form a mesh network.
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
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.
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.
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.

Programming
You can integrate your NI WSN measurement data directly into the LabVIEW
graphical development environment. After adding the WSN Ethernet gateway
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).
