HOBOnet Rainfall (inches) Sensor
$389.00 USD
A wireless sensor that records rainfall in 0.01-inch increments; communicates data to the HOBO RX3000 or the HOBO MicroRX station; preconfigured and ready to deploy.
Important Information
A complete system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor OR one HOBO MicroRX Station (which has an integrated HOBOnet Wireless Manager) and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters (RXW-RPTR-xxx or RXW-RPTR-B-xxx) can be added to extend the range.
Overview
Records rainfall in 0.01-inch increments. HOBOnet wireless sensors communicate data directly to the HOBO RX3000 or the HOBO MicroRX station, or pass data through other wireless sensors back to the central station. They are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset's innovative cloud software platform.
