HOBO MX2307 Bluetooth Soil Moisture and Temperature data logger is low-cost, fully integrated soil moisture, temperature logger 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 data loggers are ideal for researchers and growers looking for the accurate volumetric water content 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 soil moisture 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.
