Apogee Instruments ApogeeConnect software for MAC iOS versions 10.11 and above is a great tool for interfacing with Apogee’s line of USB sensors including our quantum sensors, pyranometers, and UV sensors. Features include real-time readings, graphs, datalogging (with customizable sampling and logging intervals), and the ability to initiate unattached field-logging, where the sensor head stores up to 10,000 readings when attached to a “always-on” USB power supply.
