The MX2309 pairs research-grade sensing with wireless convenience, integrating the renowned LICOR
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 400–1100 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 MX2309 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 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.

Expand your remote monitoring by adding an MX Data Plan, which allows you to upload data to LICOR
Cloud remote software for further analysis, sharing, and more.
