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.

Blog

• 17.03.2017 - YEInt'st saabus raudvara. RPi sai omale W10 peale.
