Urban agriculture is faced with the big challenge of ensuring the best growing conditions and with minimal use of resources in a limited urban setting. The design and implementation of the IoT-Based Urban Agriculture Container Farm (IUACF) is a smart farming system based on the DHT-11, MQ-135, LDR, and ESP8266 microcontroller, which monitors air quality, light intensity, and temperature and humidity in real- time and provides alerts about the need to water plants and turn on lights, respectively. The information is sent to a cloud service, where it is supervised remotely with the help of automatic feedback in order to keep crops in the best possible state. The essence is to maximize the utilization of water and energy in urban container farming with the basic crops to include spinach, carrot, capsicum, and cucumber. The experimental outcomes indicate that IUACF realized 28 percent water and 15 percent increased crop production than traditional farming systems that used man power, and at the same time under 18 kWh/month of energy consumption is enough to operate a typical system. Modular design and wireless cloud integration enable the system to support smooth decision making that is data-driven and is scalable. These results show that the suggested IoT solution can significantly boost sustainability and efficiency in urban agriculture to offer a highquality framework on future Smart City food production programs.
