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 measurement node offers four analog input channels and two to four digital I/O channels that you can configure for input, sinking output, or
sourcing output. With graphical NI LabVIEW software, you can easily configure your network, collect measurement data, trigger alarms through SMS or e-mail, and even view
monitoring data within a Web browser.

Application and Technology
Power
You can power the NI WSN measurement nodes with four 1.5 V AA alkaline battery cells, delivering three-year battery-powered operation at a one-minute sample interval. The NI
WSN-3226 also supports 1.5 V AA lithium cells. Each node features an external power port, so you can provide line power or use other forms of power such as solar or vibration
