Temperature Controlled Prototype

Update On Process 28/02/24 This week marked the commencement of the practical phase of the project, as I delved into the workshop to initiate work on the prototype. The first task on the agenda was to prepare the cooking oil drum, which will serve as the primary structure of the composter. To ensure a clean and sanitised foundation, I utilised a straightforward solution of Fairy liquid and hot water, meticulously scrubbing the interior of the drum until it was devoid of any contaminants. With cleanliness achieved, I equipped myself with curved tin snips and donned a welding glove for safety precautions. With precision and care, I began the process of cutting the top portion of the oil drum, a critical step in shaping the composter. As the snips glided through the metal, the drum gradually transformed, leaving behind a barrel-like structure that forms the core of the composter's body. This initial phase sets the stage for further development and assembly, marking the tangible commen...

Code For Arduino  The code embedded within the Arduino microcontroller orchestrates the intricate temperature regulation process within the composting prototype. Its primary function is to maintain optimal temperature conditions for composting by activating or deactivating the heat mat as needed. Upon detecting a temperature drop below the predefined threshold (exact temperatures pending further testing and analysis), the code triggers the heat mat to switch on, thereby replenishing warmth within the composting environment. Conversely, if the temperature exceeds the upper limit, the code instructs the heat mat to deactivate, preventing overheating. Additionally, the code incorporates a data logging feature, capturing temperature readings at predetermined intervals. These recorded data points are then exported to Excel for comprehensive analysis and monitoring of temperature trends over time. The code ensures precise temperature control and facilitates data-driven insights into the ...

 KTC Cooking Oil Drum (Used for the Temperature Controlled Prototype Body) The choice of the 20-litre KTC Vegetable oil drum stems from its robust construction and suitability for repurposing. Its durable metal exterior provides a sturdy enclosure for the insulation layers and heating pad, ensuring stability and protection against external elements. Moreover, the cylindrical design of the drum aligns well with the envisioned prototype model, facilitating the installation of components and allowing for efficient heat distribution throughout the composting material. With this resourceful solution, I aim to demonstrate the feasibility of temperature control in composting processes within this space, paving the way for scalable and environmentally friendly solutions in waste management and sustainable agriculture. Initially Implementing the Drum To kick off the implementation of the drum, I'll start by ensuring it's thoroughly cleaned to eliminate any traces of its previous content...

 Control System for Temperature-Controlled Prototype  "Read Me" Instructions For The Control System  Temperature Measurement: The temperature sensor installed inside the temperature-controlled prototype will measure the internal temperature. Data Processing: The temperature readings from the sensor will be transmitted by wire to the Arduino microcontroller unit for processing. Arduino Program: The Arduino will be pre-programmed with a control algorithm designed to regulate the temperature inside the prototype. Temperature Thresholds: The Arduino program will define temperature thresholds for activating and deactivating the heating system. If the measured temperature falls below the lower threshold, indicating it's too cold, the system will initiate heating. Conversely, if the temperature exceeds the upper threshold, signalling it's too hot, the system will deactivate the heating. Heating Activation: When the temperature is below the lower threshold, the Arduino wi...

 Key Meeting 20/02/24 Today, I had a productive meeting with my supervisors to discuss potential enhancements for my temperature-controlled composter prototype. One of the key points we focused on was the implementation of a simple control system to automate the heating process. The proposed system involves periodic temperature measurements within the composter. If the temperature falls below a certain threshold, the heating system will activate to maintain optimal conditions for composting. Conversely, the heating system will deactivate if the temperature exceeds the desired range to prevent overheating. This automated control mechanism is to streamline the composting process, ensuring consistent temperatures for efficient decomposition while minimising manual intervention.

This cutout reveals how the layers will be arranged within the prototype to ensure effective insulation. Each layer has a specific role in regulating temperature and enhancing ...

 Composting Restraints Within University Project In navigating the parameters of this university project, one significant limitation has emerged: the impossibility of composting actual organic matter due to its inherent biohazardous nature. This restriction presents a challenge as composting stands at the very heart of what I seek to enhance and refine. Nevertheless, I am adapting by redirecting my focus towards other critical facets of the prototype, particularly the regulation of temperature and the optimisation of insulation efficiency. While it is disappointing not to engage directly in the composting process, I am confident that exploring alternative testing methodologies will still yield valuable insights into the overall viability and efficacy of the temperature control mechanism. Through innovative approaches and experimentation, I aim to gain knowledge and push the boundaries of what is achievable within the framework of this project. Tests I Can Do Controlled temperature ...

 Cork Insulation  Natural and Sustainable Material : Cork is a renewable and sustainable material harvested from the bark of cork oak trees. Its extraction process doesn't harm the trees, which continue to grow and produce more cork. Utilising cork aligns with environmentally conscious practices, essential for promoting sustainability in your prototype. Excellent Thermal Insulation Properties : Cork insulation boards have low thermal conductivity, meaning they effectively reduce heat transfer. This property helps maintain stable temperatures within the composting environment, crucial for optimising the composting process. By minimising heat loss, cork insulation ensures that the internal temperature remains within the desired range for efficient composting, especially in colder climates or during temperature fluctuations. Moisture Resistance : Cork naturally repels moisture, which is beneficial for maintaining insulation effectiveness over time. Moisture-resistant insulation i...
