Terrestrial Use Case Hardware

This is version 31. It is not the current version, and thus it cannot be edited.
[Back to current version]   [Restore this version]


Info

Below find details on the terrestrial usecase hardware, some pictures from a dry run setup, screenshots of an example Kepler workflow using the RBNBToKepler2 actor and the resulting plots. The CRBasic program used to collect these data is also posted below.

Note: Don't try to read too much into these plots--data were collected indoors, from hardware that was occasionally moved about, powered off, etc. The program I use to push data into my RBNB server and the RBNBToKepler2 actor were both being modified as well.

Hardware

For sensors see further down the page.

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. You can easily see when I switched from AC to solar near the beginning of the battery voltage plot. Sensors and the solar panel were occasionally arbitrarily moved about. We had one cloudy day.

Rain Campbell Tipping Bucket Rain gage TE525MM-L mm forgot to plot this one initially, plot covers more time than others. Manually activated switch once; no rain inside my office yet.

This is the CRBasic program running on the CR800 doing the sampling.
