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.
