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

HOBO MX Soil Moisture Data Loggers are the industry’s only 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.

Accurate Data, Easily

Get the measurement accuracy you need – wherever you need it – without having to remove loggers from their deployed locations to offload data. All you need is a mobile phone, tablet, or Windows computer running the free HOBOconnect app. No cables to connect!

Legendary Reliability

HOBO MX2300 temp/RH and soil moisture loggers are built to withstand the elements. They feature a rugged weatherproof housing designed for long-term studies – even in harsh climates. Their compact size and built-in mounting holes make deployment simple, with no need for mounting brackets in most cases. Plus, wireless communication means there's no need to open the loggers in the field and risk compromising the weatherproof seal.

Choice of Models

The HOBO MX2300 Series offers seven models, covering a broad range of outdoor monitoring applications, from agricultural research to forest ecology studies. The series includes internal sensor models that are highly durable and easy to deploy, and external probe models that are well-suited for monitoring conditions in soils, water, walls, and more.
