The research, titled Development of Controlled Environment Chamber for Carrot (Daucus carota L.) is dedicated at individuals with an interest in cultivation with limited area and explores innovative farming techniques. The study caters to small-scale farmers and urban environments facing small outdoor areas. By using controlled environment chamber, this device design to increase crop yield and grow plant in a controlled and small period. The method applied in study are developmental, involving a process of designing, testing, and refining the controlled environment chamber system to make sure that it is effective in growing carrots. This study would address the issue of agricultural sectors after a calamity and, at the same time, test the effectiveness of a controlled chamber in growing carrot crops as an alternative to the environment that was required for them to grow by using 12V dc RGB lighting as an alternative to sunlight for carrots and a Refrigerator system for its cooling features. The possible agricultural areas that were suitable for growing carrots were diminishing because of the following problems: global warming, urbanization of lands, and commercial activities. By using a controlled chamber in cultivating carrots in tropical areas, it could lead to more opportunities for farmers and offer more jobs that were needed by many people. Considering the broader context of the device's acceptability, the weighted means for functionality, reliability, maintainability, durability, and safety were analyzed. The results indicate that all variables received high scores, with functionality scoring 4.73, reliability 4.49, maintainability 4.48, durability 4.23, and safety 4.56, resulting in an average weighted mean of 4.50 across all variables. This comprehensive assessment underscores the device's robust performance and its strong alignment with user requirements, categorizing it as "Very Much Acceptable" across the board. The study started by inserting Advance RGB Light that tailored to provide required illumination for the carrot to ensure that it will receive enough light that is crucial for their growth. Furthermore, as compared to the traditional lighting method, the Advance RGB Light offers energy saving and provides more control to the user for precise adjustment of intensity of light. It has refrigeration system that provides the required temperature within the chamber for optimal carrot growth. This achieved through an automated process that regulates the system's operation based on the ambient temperature readings from the thermocouple. This automated feature ensures that the refrigeration system operates efficiently by deactivating and activating as needed, providing the ideal temperature for the successful carrot growth. The thermocouple sensor is essential part for the efficient operation of the refrigeration system. It gives information on the ambient temperature of the chamber which is essential for the activation and deactivation of the refrigeration system. It also enables users to monitor real time temperature of the chamber assuring the optimal condition of the chamber. The moisture detector sensor send signal to the irrigation system by sending vital information regarding the soil moisture levels. The information receive will determine if the soil is low moisture or high moisture, which allows precise watering of the carrots in the chamber. The moisture detector helps irrigation system function efficiently by sending feedback on moisture levels on soils promoting the growth of the carrots. And at last, it has automated irrigation for watering carrots is designed to provide precise water distribution, ensuring the optimal growth and wellbeing carrots within the chamber. By automating the irrigation system, it reduces the human intervention of inside the chamber enhancing the efficiency and minimizing the loss of energy on refrigeration system. To maximize the potential for plant growth within a controlled environment, experts suggest utilizing high-quality lighting with specific characteristics and adjusting the light orientation to enhance light intensity exposure for the plants. By implementing these modifications, researchers aim to optimize the conditions for plant growth and achieve superior outcomes in cultivation experiments. It also enhances the efficiency of the cooling system; the researchers propose the implementation of enhanced insulation to reduce energy dissipation within the chamber. And to enhance the chamber's specifications and lessen the requirement for manual work, the researchers suggest implementing an enhanced system in the water pump that eliminates the need for frequent refills. This modification aims to streamline the process and make it more efficient, thereby reducing the workload on individuals managing the chamber.
