HOBO® RX Wireless Sensor Network
HOBO RXW Repeater (RXW-RPTR-xxx) Manual
22249-2
The HOBO RXW Repeater is designed to work with the HOBO RX Wireless Sensor Network in
which data is transmitted wirelessly from sensor motes across the network to the RX3000 station
and then uploaded to HOBOlink® web-based software. The repeater is ideal when there is an
obstruction between motes and the station or for extending the transmission range of motes in
the network. With HOBOlink, you can monitor the network, view graphs, set up alarms, download
data, and more.
