In recent years, urban farming has garnered increased attention due to rising consumer demand for locally sourced food and a collective effort to reduce carbon footprints. Singapore's government, in line with initiatives like the Green Plan 2030, is actively pursuing environmental sustainability. By championing urban farming and aligning with the principles of the Green Plan 2030, Singapore exemplifies a forward-thinking approach to environmental stewardship. This involves leveraging urban space for agricultural production and integrating innovative technologies. This thesis aims to evaluate and enhance urban farming systems utilizing solar energy for efficient investment and operation. The proposed framework is founded on a comprehensive system model that takes into account solar energy utilization and environmental performance in urban farming. While existing solar systems on the market are often costly and primarily employed in large-scale farming, the challenge lies in integrating multiple low-cost sensors with microcontrollers, such as the BeagleBone Black (BBB). ThingsBoard serves as the platform for monitoring and controlling various aspects of the system. Initial setup encountered challenges including irregular analog sensor readings and unstable WiFi connections when utilizing a single-board microcontroller like the ESP8266. However, these issues were successfully addressed. To illustrate the proposed framework, a case study was conducted on the design and operation of solar panels in various locations for assessment. Results indicate that the efficacy of solar panels and batteries in powering the system holds promise as a viable farming solution for Singapore.
