USER GUIDE AND SPECIFICATIONS

NI WSN-3202

NI Wireless Sensor Network 4-Channel, 16-Bit Analog Input Node

This user guide describes how to use the NI WSN-3202 analog input node and lists its specifications. 
Figure 1 shows the NI WSN system components.

Figure 1.  

NI WSN System Components

The NI WSN-3202 is a four-channel, low-power, wireless voltage input device that works with other 
NI WSN-32

xx

 nodes and gateways to form a wireless sensor network. The NI WSN system consists of 

one or more NI WSN gateways, up to 36 NI WSN-32

xx

 nodes per gateway, and multiple PCs or 

Programmable Automation Controllers (PACs) to receive and analyze the distributed sensor data. For 
more information about PACs, visit
