The HOBO Pro v2 Temperature/Relative Humidity data logger is a weatherproof data logger with built-in temperature and relative humidity sensors. The Relative Humidity sensor provides superior durability in humid environments.
The HOBO Pro v2 External Temperature/Relative Humidity Data Logger is a weatherproof data logger with an external Temperature and Relative Humidity sensor on a 6-foot cable for fast sensor response and deployment in tight spaces. The Relative Humidity sensor features fast response and superior durability in humid environments, and is user-replaceable.
The compact HOBO MicroRX Station is an easy-to-deploy, low-cost cellular solution for long-term, reliable monitoring of indoor conditions in warehouses, cold storage facilities, data centers, museums, commercial and residential buildings, and more. The station includes an integrated HOBOnet Manager, for easy deployment with wireless HOBOnet sensors. The station also features 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.
The HOBO RX3000, Onset’s most flexible remote data logging station, provides instant access to site-specific environmental data anywhere, anytime via the internet. The station combines the versatility and sensor quality of more expensive systems, an onboard LCD display, and the convenience of plug-and-play operation. The RX3000 is a configurable system (see "Configure System" tab below).
Only need cellular? For a cellular-only solution, the HOBOnet MicroRX Station (RX2105) offers easy-to-deploy, affordable, wireless indoor monitoring.
The HOBO MX1104 multi-channel data logger measures and transmits temperature, relative humidity, and light intensity data wirelessly. It also includes an external analog input to attach a variety of additional sensors.
This self-contained wireless data logger lets you use your mobile device and Onset’s free HOBOconnect app to access data, at any time, over a 100-foot range via Bluetooth Low Energy (BLE) technology. You can configure the logger, read out data, view data in graphs, check the operational status of loggers, configure alarm notifications, and share data files – all with no dedicated equipment beyond a mobile device. And if used with the new MX Gateway, you can remotely access your data in Onset’s cloud-based HOBOlink® software.

The HOBO MicroRX Water Level Station is a cellular, web-enabled water level monitoring solution for stormwater, floodwater, irrigation, hydrologic, and environmental applications. Pre-programmed water flow formulas for select weirs, flumes, and a stage discharge table result in an easy and intuitive configuration.
New water flow and accumulated rainfall calculations, which are performed directly on the station at time of measurement, trigger immediate notifications of critical water level conditions.
The compact and durable station, together with the non-vented water level sensor, enables harsh condition deployments and reliable monitoring. The optional integrated solar panel or battery power, with a wide range of plug-and-play smart sensors, supports flexible environmental monitoring.
The compact and rugged HOBO MicroRX Station is an easy-to-deploy, low-cost cellular solution for long-term, reliable field monitoring. Two power source options are available: a solar panel for extended deployments, and user-replaceable batteries for flexible mounting in covered or protected locations. The station includes inputs for up to five of Onset’s research-grade plug-and-play sensors, and can be ordered with an additional water level sensor input with integrated flow conversion. 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.
