Rapid urbanization and growing demands concerning food production, it is necessary to use sustainable agricultural practices, one of such sustainable practices is represented by vertical farming, where IoT technology offers an efficient approach for Controlled Environment Agriculture (CEA). This paper presents a comprehensive review and design of a low cost IoT-based smart vertical farming using ESP32 microcontroller and Blynk cloud platform. The proposed system integrates multiple sensors including soil, moisture, temperature, humidity, pH and Total Dissolved Solids (TDS) to enable real-time monitoring and automated control of irrigation, nutrient supply and environmental conditions. Unlike existing systems that are largely conceptual or limited to hydroponics, this work emphasizes practical implementation, cost effectiveness, and full automation.
