Onset HOBO RXW-RGE-900 HOBOnet Wireless AeroCone Rain Gauge (Imperial) for RX3000 Stations measures rainfall and is designed to work with the HOBOnet Wireless Sensor Network, in which data is transmitted wirelessly from the sensor mote across the network to an RX3000 station and then uploaded to HOBOlink web-based software. With HOBOlink, you can monitor sensor readings, view graphs, set up alarms, download data, and more.
