Duş alırken suya açtığınızda suyun sıcaklığının artıp artmadığını bu sensör projesi ile takip edebilirsiniz. Böylece soğuk su yada çok sıcak su olduğunu canınız yanmadan anlayabilirsiniz.Proje arduino ile yapılmış. Analog bir giriş kolay bir şekilde kullanılarak ledlerin yanmasını sağlıyor.
Bakır plaketi devreye breadboard haricinde kurmak isterseniz kullanabilirsiniz. PCB dosyaları yazının en alt kısmına eklendi. Sensörü direk suyla temas ettirmeniz daha iyi olacaktır. Suyun sıcaklığını kolaycan anlamanıza yardımcı olacaktır. Arduino boardunuzun suyla temas etmemesine dikkat edin.
1 Arduino UNO
7 kırmızı led
3 yeşil led
10 220ohms direnç
1 9 volts pil
1 bakır plaketi
1 sıcaklık sensörü tmp36 yada lm35
1 10kohms potansiyometre
Duş başlığına resimde ki gibi monte edebilirsiniz.
