Collecting environmental data
We were looking to collect some data that then may be the source for the render output of our other projects: vPiP drawing machine, G-code pen plotter and RGB LED Grids.
A few of us have built portable environmental data sensors with GPS tracking that I detail here.
The thought that these units could then be cycled around the local area or left statically for a period to collect the data.
