Solar-powered IoT aquaponics
Solar-powered aquaponics design with ESP32 telemetry and a connected monitoring dashboard.
01 / CONTEXT
The challenge.
Aquaponics combines several interacting physical needs: water circulation, lighting, level regulation, and a reliable energy supply. Monitoring and actuation need to work together.
02 / PROCESS
The approach.
- The original study combines ESP32 monitoring, environmental sensors, a web interface, and solar-energy sizing for an aquaponics system.
- The maintained software connects ESP32 HTTP telemetry to a validated FastAPI service, SQLite storage, history queries, and a telemetry WebSocket.
- The dashboard separates hardware, manual, and simulated samples, flags stale values, and exports timestamped readings.
- Raw voltages remain distinct from calibrated units. Missing measurements are not replaced with random values, and local configuration holds device credentials.
03 / REFLECTION
The outcome.
The project study describes a 70 W solar array, 100 Ah battery, and 4.6 ± 0.2 A charging current. Estimated solar coverage is 67.8% of a 352 Wh/day load. SmartAqua combines ESP32 telemetry with a local monitoring dashboard, documented setup, and tested backend APIs.
Project scope
The energy estimate excludes controller consumption. Dashboard demo readings are synthetic and clearly labelled. Team: Alazar Wake, Eden Yoseph, Filmon Nezif, and Yordanos Mekonen. A first-page paper preview is available below.
