Wireless Sensor Network (WSN) Measurement Nodes

NI wireless sensor network (WSN) measurement nodes offer low-power, reliable operation for long-term, distributed deployments. The measurement nodes feature direct sensor connectivity and a 2.4 GHz radio to wirelessly transmit data to the NI WSN-9791 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.

A low-power microprocessor delivers operation and control of the measurement nodes. You can power the nodes with four 1.5 V, AA alkaline cells for up to three years of operation on battery power, or you can externally power them with a 9 to 30 VDC supply. Up to 36 measurement nodes can connect to a single WSN-9791 Ethernet gateway, with outdoor range up to 300 m with line of sight.

NI-WSN software delivers easy network configuration with the NI Measurement & Automation Explorer (MAX) utility and data extraction with NI LabVIEW software. You can customize the behavior of the programmable NI WSN measurement nodes using the LabVIEW Wireless Sensor Network (WSN) Module Pioneer to create simple node intelligence that extends battery life, interfaces with sensors, achieves higher analog input rates, and responds to digital value change events.
