Specifications
These specifications are typical from –40 to 70 °C, and assume high rejection strength mode and
50/60 Hz filter rejection mode unless otherwise noted. Some specifications (such as sample interval and
power consumption) can be optimized by customizing node behavior with the NI LabVIEW Wireless
Sensor Network (WSN) Module Pioneer. Refer to the
LabVIEW WSN Pioneer Performance
Benchmarks
document, at
zone.ni.com
for more information.
For the NI WSN gateway specifications, refer to the gateway documentation.
