  • OVERVIEW

    Experience high-accuracy environmental monitoring like never before with the MX2308 Temp/RH/PAR Logger. Engineered for precision, this rugged, Bluetooth-enabled device measures photosynthetically active radiation (PAR), temperature, and relative humidity, making it an indispensable tool for growers, researchers, and innovators. From optimising commercial greenhouses to supporting cutting-edge agricultural research, the MX2308 empowers you with actionable data to enhance growth, productivity, and sustainability.

    High-accuracy PAR measurement for optimal growth

    The MX2308 integrates seamlessly with the LI-COR® 190R PAR sensor, the trusted industry leader in light measurement. Its precision allows you to track PAR levels accurately to optimise photosynthesis and maximise growth in a variety of agricultural and research conditions.

    Expand your capabilities with an optional MX Data Plan, which uploads data to the LI-COR Cloud for remote analysis and sharing. This feature is ideal for teams looking to collaborate and gain deeper insights into their data.

    Take the complexity out of environmental monitoring with the MX2308 Temp/RH/PAR Logger. Whether you’re managing commercial farming operations or conducting field research, this device ensures you always have reliable, actionable data at your fingertips.

    Features

    • Wireless Bluetooth data offload enables quick and seamless setup and data retrieval via phone or tablet, with a range of up to 100 ft.
    • High-accuracy PAR measurements provided by the integrated LI-COR PAR sensor ensure precise light intensity readings for both natural sunlight and indoor grow lights.
    • Integrated temperature and RH monitoring captures temperature and humidity alongside PAR data, offering VPD calculations for a comprehensive view of greenhouse climate conditions.
    • Rugged, weatherproof design with IP67/NEMA 6 housing withstands humid, wet, and dusty environments in greenhouses, growth chambers, and outdoor field sites.
    • Long battery life and memory with a user-replaceable battery lasting over two years and ample storage capacity for extended deployments.
    • Alarms and alerts allow proactive monitoring, with LED readouts for out-of-range conditions and configurable threshold alerts in the HOBOconnect app.
    • Easy deployment ensures quick setup with user-friendly logging interval configuration and wireless data access directly in the field using the HOBOconnect app.

    Versatile solutions for growers, researchers, and innovators

    • For Growers and Farmers: Achieve consistent yields and reduce disease risk by monitoring critical growing conditions in greenhouses, vertical farms, and hydroponic systems.
    • For Researchers and Educators: Harness research-grade data for agricultural studies, plant science experiments, and academic teaching without the complexity or cost of traditional setups.
    • For Ag Tech and Innovation Teams: Use the device’s adaptability for prototyping or deploying scalable trials in lighting and climate control solutions.

    Important:

    The HOBO MX2300 data loggers require the HOBOconnect App and a compatible mobile device. The system requirements for the HOBOconnect app can be found at the bottom of our HOBOconnect software page.
