Idee

Luua ilmajaama veebiteenus.

Vajalikud komponendid:

  • REST teenus
  • REST Teenuse kliendiks on RPi(2|3) W10, mis teeb sensori (SparkFun Weather Shield) andmetega XML POST päringuid REST teenuse suunas
  • Presentatsiooni kiht, mis visualiseerib REST'i andmed.
  • Presenteerivaks seadmeks on tavaarvuti või RPI3 7" W10'ga

Projekt

Ülesanne

  • Tuvastatud kasutaja saab ilmajaama andmedi lisada, kuvada ja kustutada
  • Tuvastatud kasutaja saab REST teenusega lisada andmebaasi ilmajaama andmedi.
  • Anonüümne ja tuvastatud kasutaja saab ilmajaama sensoriandmedi filtreerida asukoha ja perioodi järgi
  • Tuvastatud kasutajajid saab lisada gruppidesse (Riik, Maakond, Vald, Linn, Linnaosa)
  • Tuvastatud kasutaja andmeid saab muuta
  • Igal tuvastatud kasutajal on oma sensoriadnemetega "töölaud" (dashboard)
  • Tuvastatud kasutaja saab oma ilmajaama andmed (dashboard) anonüümselt jagada.
