These New HOBO MX2306 & MX2307 Soil Moisture Data Loggers are the industry’s only low-cost, fully integrated soil moisture loggers with Bluetooth wireless data offload.
They are available in two models – one that measures soil moisture (HOBO MX2306) and one that measures both soil moisture and temperature (HOBO MX2307).
These data 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.
Using just a mobile phone, a tablet, or a Windows laptop running Onset’s free HOBOconnect app, the users obtain convenient wireless setup and data downloads via Bluetooth when within 100 feet of the logger. This makes 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.
The MX2306 & 2307 data loggers require a compatible mobile device or Windows computer and the use of HOBOconnect app.
The System requirements for the app can be found at bottom of the HOBOconnect software page.
* 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.
