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 soilmoisture 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 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 cloudbased HOBOlink software.
- Ready to deploy, with pre-attached sensors
- Easy configuration and data offload with the free HOBOconnect app
- Durable TEROS 10 soil moisture sensor lasts over 10 years in the field
