Liquid Dispensing¶
Purpose¶
Doses nutrient concentrates, pH-up, or pH-down solutions into the reservoir in response to sensor readings.
Hardware¶
- Component: TBD (e.g. peristaltic pumps)
- Interface: GPIO relay per pump
Control Logic¶
- Triggered by: pH / EC sensor deviation
- Output: timed pump pulse (volume by duration)
- Safety: minimum interval between doses to avoid over-correction
