With my working during the intensive week, I have completed the prototype system with the following features:
- Ebb and flow hydroponic system with peristaltic pump
- RGBW lighting with SK6812 chips and custom made PCB
- Air, power delivery and wiring
- Sensors (ambient temperature and humidity, water temperature)
- Cooling unit to test the electronics choices
- MQTT system with EC2 server with custom domain
- MQTT msg handling with node-red
- Smart phone dashboard with MQTT Dash
- PC dashboard with node-red dashboard
Deployment environment photo also updated in the project.
During the two weeks of evaluation , a few issues pop out and forced me to stop the testing. A list of issues are stated below
- The LED tends to heat up quite hot. Thermal management should be in place to extend the life of LED panel
- The peristaltic pump form black particular in the rotation parts and possible damage of rolling parts. The speed of peristaltic pump should be reduce
- The planter have serious grow of algae and rusting occur. Plastic planter will be explore in the coming version
