Rugged and Bluetooth-enabled, the MX2308 delivers research-grade monitoring of key growing conditions—photosynthetically active radiation (PAR), temperature and relative humidity—all in a single device. Whether you’re growing plants in a commercial greenhouse, managing indoor vertical farms, fine-tuning conditions in hydroponic systems, or conducting agricultural or ecological research, the MX2308 gives you the data you need to optimise conditions for growth, health, and productivity.
Built for simplicity and flexibility, this all-in-one logger integrates with the LI-COR® 190R PAR sensor, the industry standard for light measurement that's trusted by researchers worldwide for its precision in measuring photosynthetically active radiation (PAR). This versatile logger is designed to operate reliably across diverse environments, from high-tech vertical farming racks to outdoor experimental plots to support informed decisions around lighting, ventilation, and irrigation without the complexity or high costs of traditional monitoring systems.
Key Features
All-in-one Environmental Monitoring - Measures temp, RH, and PAR with research-grade accuracy.
Derived parameters - Calculates key metrics like Daily Light Integra (DLI) and Vapor Pressure Deficit (VPD) to optimize crop health and yield.
Wireless Bluetooth Data Offload - Fast, easy logger setup and download via phone or tablet (up to ~100 ft range).
Rugged, Weatherproof Design - Durable IP67/NEMA 6 housing stands up to humid, wet, and dusty environments found in greenhouses, growth chambers, or outdoor field sites.
Long Battery Life & Memory - User-replaceable battery lasts up to ~2+ years and ample data storage supports extended deployments.
Alarms and Alerts - See out-of-range conditions with logger's LED readout, and configure threshold alerts using HOBOconnect for proactive monitoring.
Easy Deployment - Users can deploy the logger in minutes, configure logging intervals via the HOBOconnect app, and wirelessly retrieve data (without a laptop) in the field!
Examples of Monitoring Applications for the MX2308 Temp/RH/PAR Logger
Growers, Farmers & Producers:
Helps optimize growing conditions, improve yield consistency, and reduce disease risk for commercial greenhouse and indoor farming operators and hydroponic/aquaponic growers by monitoring where it matters most.
Researchers & Educators:
Wireless setup and data retrieval enable flexible deployment across experimental sites, with data quality ideal for agricultural researchers, plant scientists, and university programs without the budgetary or logistical barriers typical of research-grade systems.
Ag Tech & Innovation Teams:
Ease of deployment and integration-ready data formats make an ideal sensor platform for prototyping or scaled trials needed for companies innovating in lighting optimization and climate control solutions.
Setup and data retrieval are seamlessly simple—no cables or additional download devices needed using the free HOBOconnect app on your phone or tablet. Effortlessly configure the logger and download data via Bluetooth (up to a 100 ft range), which allows you to deploy in and download data from hard-to-reach spots.
Requires a compatible mobile device or Windows computer and the HOBOconnect app.
