Abstract

The hydroponic bio-enclosure is a self-contained device designed to provide the user with both ebb-and-flow and deep water culture hydroponic growing methods. The device is semi-autonomous and can be monitored and controlled directly from a computer. Furthermore, it grants monitor and control of light, temperature and humidity values to the user, ensuring the optimal growth conditions are constantly maintained. The system uses a central and reservoir and pump to deliver nutrient solution to the plants as needed.These components are modulated by a central control system in the form of an Arduino Nano ESP32. Submerged sensors are used to detect temperature, humidity and flow values and provide feedback to the controller. The system then activates the necessary components in order to maintain the designated settings provided by the user. In optimal conditions, the system is able to run for weeks at a time without user intervention. The most frequent necessary interaction involves changing the growth solution, as the plants gradually absorb and thus dilute the nutrients contained therein. Cleaning and maintenance is also required on a designated basis. The prototype model manufactured as a part of this project was constructed using reclaimed wood and off-the-shelf parts, aiming to minimize cost and carbon impact.
