The NI WSN-3226 measurement node adds resistance-based measurements, such as those from RTDs and potentiometers, to the NI wireless sensor network (WSN) platform. Using the node, you can combine temperature and voltage measurements on a single device. The WSN-3226 provides four analog input channels that you can configure on a per-channel basis for 10 V measurements or resistance-based measurements. The device also features two bidirectional digital channels with industrial voltage ranges that you can configure on a per-channel basis for input, sinking output, or sourcing output. The 18-position screw-terminal connector delivers direct connectivity to sensors, and the device offers a 12 V, 50 mA sensor power output to drive sensors requiring external power. You can power the measurement node with four 1.5 V, AA alkaline or lithium battery cells, with operation for up to three years on battery power, or you can externally power the node with a 5 to 30 V supply (not included).
The WSN-3226 also features 50/60 Hz filtering and two operational modes, high speed and high resolution, so that you can optimize power and throughput trade-offs for your application. Additionally, the device supports battery backup; in the event external power is lost, the device automatically switches over to battery power.
A 2.4 GHz radio is used to wirelessly transmit data to the WSN gateway, where you can connect through Ethernet to other network devices. NI-WSN software delivers easy network configuration in NI Measurement & Automation Explorer (MAX) and data extraction with NI LabVIEW software.
You can configure the WSN-3226 as a mesh router to increase network distance and connect more nodes in your WSN system. You can connect eight end nodes (star topology) or up to 36 measurement nodes (mesh topology) to a single WSN gateway, with outdoor range up to 300 m with line of sight. The device also offers industrial temperature and shock and vibration ratings.
