Project DescriptionOur product is a control system which would not only monitor the plants and fish in their

symbiotic ecosystem, but also either correct the problem or notify the owner that specific actions

need to be taken. The system will monitor and adjust various aspects of the environment such as;

water temperature, oxygenation, lighting, and water quality. Control of grow- light timing and

monitor soil moisture content would also be included, and necessary fish food and nutritional

additions can also be periodically added to the system. This solution would allow even the

busiest of families to participate in supplementing their own healthy diet.

The system would be comprised of a controller, sensors, and various activators that

would correct specific issues with the ecosystem. The controller would monitor environmental

conditions and when correction is required, the system software would activate corrective

measures that would bring the system back within tolerance. When human interaction is

required, the owner of the system will be notified of the problem and the necessary corrective

actions that they need to perform.
