Table 1. WSN Node Speciﬁcations

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.

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.

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

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.
