Wireless Sensor Network Analog Input Nodes NI WSN-3202, NI WSN-3212, NI WSN-3226 Support for hundreds of nodes to help you create a reliable network to monitor your assets or environment Four analog input channels per measurement node NI-WSN software that provides easy network configuration, drag-and-drop LabVIEW programming, and support for logging, alarming, and Web-based data visualization Bidirectional digital channels; configurable for input, sinking output, or sourcing output (2 to 4 DIO channels per node) Industrial ratings: -40 to 70 °C operating temperature and 50 g shock, 5 g vibration Low-power operation, up to 3-year battery life 2.4 GHz, IEEE 802.15.4 radio that provides up to 300 m outdoor range 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.

energy harvesting. The WSN-3226 supports battery backup, meaning you can connect both external and battery power; the node defaults to external power and automatically switches to battery power in the event the external power drops below a voltage threshold. The external power input should be used to power Nl WSN nodes operating in router mode, which is a feature that you can enable in software to set up a self-healing mesh network of nodes. Router nodes increase density, distance, and redundancy in your wireless network. Each node offers bidirectional digital I/O channels for input,...
