Wireless temperature and soil moisture data – straight to your mobile device or Windows laptop

HOBO's MX2307 is a low-cost, fully integrated soil moisture and temperature logger with Bluetooth wireless data offload. The MX2306 is 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.
