Soil & Moisture
The MX2306 is a low-cost, fully integrated soil moisture 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 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.
HOBO MX2300 loggers provide a 100' wireless range, making it simple to offload data in hard-to-reach locations. And 0.2C accuracy ensures you're getting reliable, true results every time.
From environmental research to crop management, HOBO MX2300 loggers are a low-cost, accurate monitoring solution to help you improve crop yield and quality, reduce erosion and harmful runoff, bettter understand the impacts of climate change, enhance irrigation, and more!
