Wiring Diagrams
Complete visual guides for assembling your Fyto
- Use LM35, NOT DS18B20: The code requires an analog temperature sensor. DS18B20 is digital and won't work without modifications.
- Logic Level Converter Recommended: Use a 5V to 3.3V bi-directional converter to protect your Pi's GPIO pins.
- Enable I2C: Run
sudo raspi-config→ Interface Options → I2C → Enable. Also disable Serial. - Channel Assignment: The original tutorial has different ADC channel assignments. Our wiring matches the actual code: A1=Temperature, A2=Moisture, A3=Light.
- Calibrate Sensors: Use
calibration.pyto test each sensor individually before final assembly.
