Arduino ve Processing İle Meteoroloji İstasyonu Projesi

Bu projemizde hava istasyonumuzu yaparak bilgisayarımızdan gerçek zamanlı grafik çıktı alacağız. Processing arayüz ile görsel olarak anlık rüzgar hızı, basınç, sıcaklık ve rüzgar yönünü takip edeceğiz.Elde ettiğimiz verileri her 10 dakikada bir jpg olarak kaydedeceğiz.

Malzemeler:

1. Arduino
2. Anemometre
3. BMP085 barometrik basınç sensörü
4. Potansiyometre
