Info

Below find screenshots of an example Kepler workflow using the RBNBToKepler2 actor and the resulting plots. This is junk "desk data"--the Campbell CR800 datalogger

and sensors are set up and running on my desk. You can easily note when I switched from AC to solar near the beginning of the battery voltage plot. Sensors and the solar panel were/are occasionally arbitrarily moved about, though it was fairly infrequent (in the case of the panel, generally to better sit in sunlight). We had one cloudy day. The program used to collect these data is also posted below.

Plots

All times are in seconds since unix epoch. This will be remedied in the future, it requires a fair amount of development to be implemented properly.

Air Temp	Campbell	Temp & RH Probe #1	CS215-L	Deg C	inside Gill Radiation Shield
Relative Humidity	Campbell	Temp & RH Probe #1	CS215-L	%	inside Gill Radiation Shield
Battery Voltage	Campbell	(12V Power Supply w/ Voltage Regulator)	(PS100)	Volts
Line Photosynthetic Photon Flux (PPF) 1	Apogee	Line Quantum Sensor #1	LQS70-10	mV	[1]
Line PPF 2	Apogee	Line Quantum Sensor #2	LQS70-10	mV	[1]
Point PPF	Apogee	Quantum Sensor	QSO-SUN	mV	[#1] plot is mV. Sensor has standard calibration 5.00 µmol m^-2s^-1 per mV. Full sunlight is 2000µmol m^-2s^-1 (400mV). PPF = sensor output * 5.00 µmol m^-2s^-1
