- Easy configuration and data offload with the free HOBOconnect app
- Bluetooth (BLE) with optional gateway for real time alerts
- Durable TEROS 10 soil moisture sensor lasts over 10 years in the field
- For use in both mineral soils and soilless media
- Sturdy, sharp, stainless-steel spikes for easy installation and better soil contact
- Option to view data in percent of field capacity
Low-cost, fully integrated soil moisture loggers with bluetooth wireless data offload. Available in two models - one that measures soil moisture (HOBO MX2306) and one that measures both soil moisture and temperature (HOBO MX2307) - these loggers are ideal for researchers and growers looking for the accurate data they need to save water, improve crop yields, reduce harmful runoff, and protect ecosystems.
With just a mobile phone, tablet, or windows laptop running Onset’s free HOBOconnect app, users get convenient wireless setup and data download via Bluetooth when within 100 feet of the logger, making it easy to retrieve data from hard-to-access field locations. And for indoor areas such as greenhouses, users can add the MX Gateway for remote access to data in Onset’s cloud-based HOBOlink software.

Soil Moisture: Volumetric Water Content (VWC):
Measurement range: 0.00 to 0.64 m³/m³ in mineral soils; 0.00 to 0.70 m³/m³ in soilless media
Accuracy: ±0.031 m³/m³ typical in mineral soils that have solution EC <8 dS/m; ±0.051 m³/m³ typical in soilless media
Resolution: 0.001 m³/m³
Temperature sensor range (MX2307 only): −40 to +100 °C (−40 to +212 °F), with tip and cable immersion in fresh water up to 50 °C (122 °F) for one year
Temperature sensor accuracy ((MX2307 only): ±0.25 °C from −40 to 0 °C (±0.45 from −40 to 32 °F); ±0.2 °C from 0 to 70 °C (±0.36 from 32 to 158 °F); ±0.25 °C from 70 to 100 °C (±0.45 from 158 to 212 °F)
Temperature sensor resolution ((MX2307 only): 0.04 °C (0.072 °F)
Certifications: The sensor data can be post-calibrated if necessary (e.g. the sensor is used in non-mineral soil types or higher than standard accuracy is required). Users can apply a calibration equation to the data exported from the app. The VWC range will depend on the calibration equation.
Accessories information: The MX Gateway (VWR #: 470323-480) links MX data loggers seamlessly to the HOBOconnect cloud-based data platform to provide real-time alert notifications for MX data loggers, automatically.
