Node sample intervals can be improved by customizing how the node samples and transmits data. 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.
