Overview
The National Instruments wireless sensor network (WSN) platform delivers low-power measurement nodes that offer industrial certifications, reliable networking, and optional
weatherproof outdoor enclosures for long-term, remote monitoring applications. The measurement nodes have direct sensor connectivity and a 2.4 GHz radio to wirelessly
transmit data to a WSN gateway. Each serial node features one serial port and two digital I/O channels that you can configure for input, sinking output, or sourcing output. With NI
LabVIEW grpahical system design software, you can easily configure your network, collect measurement data, trigger alarms through SMS or email, and even view monitoring
data within a web browser. With the NI LabVIEW Wireless Sensor Network (WSN) Module, you can customize the behavior of programmable NI WSN measurement nodes and
create an autonomous interface to serial-based sensors, instruments, and control boards. Use this module to optimize node behavior for your application: customize sample and
transmission rates, perform onboard analysis or data reduction, respond to digital value changes, perform local control of DIO lines, and even store data to flash memory.

Application and Technology
Autonomous, Programmable Serial Interface
The NI WSN-3230 and WSN-3231 measurement nodes deliver wireless connectivity to serial-based sensors, instruments, and control boards. Using the LabVIEW WSN Module
and the LabVIEW Serial Compatibility API, you can deploy graphical code to embed command, query, and parse algorithms to the node, which creates a local, autonomous
communication loop between the node and the serial device, as seen in Figure 1.
