A compact, rugged, easy-to-deploy, low-cost cellular solution for long-term, reliable field monitoring. With two power options available (a solar panel for extended deployments or user-replaceable batteries for flexible mounting in covered or protected locations), this monitoring station includes inputs for up to five of Onset's research-grade plug-and-play sensors. Configurable station-side alarms trigger immediate notifications of critical conditions, and Onset's cloud-based HOBOlink platform makes it easy to view, access, and share data. This station can also be ordered with an additional water level sensor input with integrated flow conversion.


Onset's most flexible remote data logging station, the HOBO RX3000 provides instant access to site-specific environmental data anywhere, at any time, via the internet. This configurable station combines the versatility and sensor quality of more expensive systems, an onboard LCD display, and the convenience of plug-and-play operation. (See "Configure System" tab below.)

The RX3000 station is the main component of the cost-effective and scalable HOBOnet Field Monitoring System for crop management, environmental research, and greenhouse operations.


A temperature/relative humidity sensor designed to work with all HOBO data loggers that accept Smart Sensors. All sensor parameters are stored inside the smart sensor, which automatically communicates configuration data information to the logger without any programming, calibration, or extensive user setup.

If an 8m cable is preferred, please see Temperature/Relative Humidity (8m cable) Smart Sensor.

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