• Sunlight-luminosity measurement with a single board computer (raspberry-orangepi)  + (As you might not know, the meteorological … As you might not know, the meteorological surface synoptic observations data (SYNOP, available here: https://donneespubliques.meteofrance.fr/?fond=produit&id_produit=90&id_rubrique=32) does not take into account sunlight/luminosity.
  
  Sunlight/luminosity data can be interesting to gather for a diversity of uses (home well-being, photovoltaics production, plants care,...).
  
  For photovoltaics, although the technology is old, I did not manage to find reliable measurements for cloudy weather.
  
  We find videos of such a measurement, for example this one:
  https://www.youtube.com/watch?v=H_Aow78MFmQ&ab_channel=TopeSosanya
  that may suggest that solar pannels produce at 50% of their nominal capacity.
  
  My measurement instruments being subject to interferences, I dont really trust my measurements to be reliable, so i thought about producing simple code that other users less subject to interferences could reuse at their convenience.
  
  This tutorial will allow you, with only two commands (after installing operating system and docker), to use your single board computer like a weather station recording sunlight/luminosity every minute in a database and producing a web page where results can be retrieved with date filters options.
  the demo is available here:

  Note: dont trust the measurements displayed in the demo above: the ecoterrorist french police doctrine destroys the possibility to do science correctly in france with computers. I do not have the adequate financial and technical means, and I do not want to spend time playing cat and mouse again and again to dodge recurring cyber attacks and shackles. The logic integrity of the code is good. If the system changes, or if you are not targetted too much, this could be useful.
  
  Publishing on lowtechlab is a signal to encourage you to do your own measurements with diy stuff, like a multimeter and an old offline camera to upload on youtube or peertube. If you read this tutorial and you are not yet an ecoterrorist, you have a superpower: the invisibility cape. old offline camera to upload on youtube or peertube.
