Kendali Suhu Ruangan dengan Sensor DS18b20 dan Arduino Uno
Alat&Bahan
1.Sensor DS18b20 (waterproof)
2.Arduino Uno
3.Resistor 510 Ω
4.Resistor 4K7 Ω
5.LED sebagai indikator aktuator
Kemudian buatlah rangkaian seperti pada gambar di bawah ini dengan konfigurasi pin :
•Kabel kuning/DATA ke pin A0)
•Kabel merah/VCC ke 5v dan kedua kabel ini (kuning dan merah) dihubungkan oleh resistor 4K7 Ω.
•Kabel hitam ke GND
•LED terhubung dengan pin A1.
