Terrestrial Use Case Hardware

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.

Hardware

For sensors see further down the page.

name	quantity	model	details	notes
Tripod	1	CM6	6'
Enclosure	1	enc12/14	two 1.25in conduits
Antenna	1	ANT-DB1-HDP-SMA	Dual-Band Surface Mount Dipole (Horizontal); 3dBi
Antenna	1	"Maxrad" 5 Element Yagi	9DBD
Radios	2	RF401	Spread spectrum 910.5-917.7Mhz; 38.4K Data max data rate; Maxstream - 9XStream X09-009 transceiver module	I've set both to 38.4
Power Supply with Charging Regulator	1	PS100	12Vdc, 7Ahr	don't let it drop below 10.5V

Workflow

A bit messy...

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.
