Automated Garden Watering System
Automated indoor garden watering system with sensor feedback, scheduling, and modular expansion.
Mechanical Electrical Controls Software
Result
Reduced manual watering to zero and maintained consistent soil moisture across all plants.
Overview
An automated indoor garden watering system designed to remove manual watering while maintaining consistent soil moisture.
System Architecture
- Water reservoir + level sensing
- Distribution/manifold to multiple plants
- Soil moisture sensing per plant
- Microcontroller control logic and scheduling
Mechanical
- Printed housings/manifold parts for rapid iteration
- Leak-resistant layout and serviceability
Electrical & Controls
- Capacitive soil moisture sensors
- Float switches for reservoir monitoring
- MOSFET control for valves/pumps
- Real-time clock for scheduling
Software
- Sensor-based and schedule-based watering modes
- Safety interlocks for low-water conditions
- Configurable per-plant thresholds
Lessons Learned
- Calibration beats “generic thresholds”
- Modular design makes scaling painless
- Water systems reveal edge cases fast
