Refer to the section on Node Programming for more information. 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 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. 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. 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 acquiring measurement data and controlling digital I/O. 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. 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. 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). 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. Figure 2.

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 Figure 3. Extracting NI WSN Measurement Data Using LabVIEW exceeded, which reduces response time and increases reliability by removing the need for host interaction. 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).

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 systemspecific 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.
