A complete system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager (RXMOD-RXW-xxx), and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters (RX-RPTR-xxx) can be added to extend the range.


The Davis® Rain Gauge Smart Sensors features the new AeroCone® design, for better measurement accuracy in high-wind conditions. This gauge is made from UV-stabilized ABS plastic to provide a cost-effective sensor for rainfall measurement, and is plug-and-play compatible with all HOBO weather stations.

Also available in a wireless model for use with the HOBOnet Field Monitoring System.

Highlighted Features
