Temp/RH/Solar Data Logger

Research-grade, multiparameter microclimate monitoring solution with effortless Bluetooth data offload that continuously measures global solar radiation, temperature, and humidity. Ideal for agricultural, environmental research, ecology, and energy applications.

• Wireless Bluetooth data offload: Fast, easy logger setup and download via phone or tablet (up to ~100' range)

• Research-grade Solar Radiation measurement: Integrated LI-COR 200R sensor measures total solar irradiance in the 400 - 1100 nm range with ±3% typical calibration uncertainty
• Integrated Temp and RH monitoring: Logged temperature and humidity alongside solar radiation for a complete view of environmental conditions
• Rugged weather-proof 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 and 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!

The Temp/RH/Solar data logger pairs research-grade sensing with wireless convenience, integrating the renowned LI-COR LI-200R pyranometer that delivers solar radiation measurements with scientific-grade accuracy (calibration uncertainty of ±3% typical).

This all-in-one device captures a comprehensive climate picture, combining an external LI-200R pyranometer (measuring total solar irradiance in the 400 to 1100 nm range) and built-in temperature and relative humidity sensors. This enables the calculation of critical metrics such as Accumulated Solar Radiation (MJ/ m²), Daily Light Integral (DLI of Solar, MJ/m²/day), Vapor Pressure Deficit (VPD, kPa), and Dew Point. Providing laboratory-quality measurements of solar climate conditions in an affordable, mobile logger, the rugged, battery-powered TEMP/RH/Solar data logger is easily deployed and expands monitoring capabilities to an even broader range of environmental and energy applications.

Users can mount the sensor in the field, and setup and data retrieval are seamlessly simple - no cables or additional download devices needed using the free HOBOconnect app n phone or tablet. Effortlessly configure the logger and download data via Bluetooth (up to a 100' range), which allows you to deploy in and download data from hard-to-reach spots.
