Automatic hydroponic microfarm for plant cultivation
Takács, Peter ; Janoušek, Jiří (oponent) ; Szabó, Zoltán (vedoucí práce)
This thesis deals with the implementation of hardware and software design for an existing hydroponic micro-farm. The thesis includes a literature and internet search focused on automated plant cultivation. A description of different types of soilless cultivation systems is given in the thesis. General plant requirements are addressed and these requirements are thoroughly discussed. Instrumentation using specific components is also described in the thesis. The system integrates a control unit, heating and aeration controls for the nutrient solution, adjustable lighting, and sensors for pH, EC, and adjustable water and ambient temperature. In addition, the advantages and disadvantages of two selected microprocessor units are discussed. Further, the operation of the microcontroller that controls the individual components is also described in the thesis. This thesis briefly describes the general circuitry of each component and includes circuit diagrams and the schematic of a printed circuit board. This thesis describes the program of the firmware and the functions of the web interface used to interact with the system. Additionally, it features remote control and monitoring capabilities via a web interface, with email alerts for external intervention needs. This thesis also includes the implementation of the electronics in terms of assembly and calibration.
