User's Manual

Internal Data Storage

The sensor has internal data storage capability with the ability to hold up to 10,000 measurements. This allows the sensor to collect data while connected to a stand-alone 5 V DC power supply such as a USB wall adapter.

No Datalogger Required

The sensor can be connected to a desktop or laptop computer via USB 2.0 type A plug, to be used with the ApogeeConnect software (Windows compatible, XP and later; Mac compatible, 10.10 and later). The included Apogee software gives the user control of data logging and calibration settings, provides a real time output display and graph of shortwave radiation measurements and allows the data set to be saved as a csv file.
