pH Sensing¶
Purpose¶
Tracks the acidity of the nutrient solution. pH directly affects nutrient availability; most crops target 5.5–6.5.
Hardware¶
- Sensor: TBD (e.g. Atlas Scientific EZO-pH)
- Interface: TBD (analog / I²C / UART)
Integration¶
- Polling interval: TBD
- Acceptable range: 5.5–6.5 pH
- Correction: triggers liquid dispensing actor
