Prvi korak je dobivanje tokena sa stranice podatkovne platforme .
Nakon što dobijete vlastiti token, možete koristiti sljedeću skriptu za prijenos podataka. Nakon što učitate svoje prve podatke o stanici, idite na aqicn.org/data-feed/verification/ da konfigurirate svoje stanice i provjerite učitane podatke.
Podržane softverske platforme:
Nudimo softver spreman za korištenje za te 3 platforme:
- Arduino : Ako imate Arduino CPU, koristite softver spreman za korištenje dostupan na github.com na aqicn/gaia-a08-arduino .
- Python: upotrijebite isječak koda u nastavku
- Naredbeni redak (CURL): Upotrijebite isječak koda u nastavku
Ako nemate stanicu za praćenje, a željeli biste je nabaviti, provjerite naše GAIA stanice za praćenje kvalitete zraka.
Ako više volite DIY stanicu, provjerite GAIA A08 .
