ABSTRACT
With the rapid growth in global population and the increasing pressure on agricultural resources, there is a strong need for efficient and sustainable farming solutions. Techniques such as aquaponics and hydroponics have gained attention as they enable cultivation without soil while using significantly less water. However, maintaining stable environmental and water conditions in these systems requires continuous monitoring and precise control.
This paper presents an IoT-based smart monitoring system designed to enhance the performance of aquaponics and hydroponics setups through real-time sensing and automation. The system employs multiple sensors, including pH, temperature and humidity (DHT11), TDS, turbidity, light intensity (LDR), ultrasonic, and water temperature sensors, to track critical parameters affecting both plant growth and aquatic health. The collected data is processed by a microcontroller and transmitted to a cloud platform for visualization and remote access.
An automated control strategy is implemented using predefined threshold values, enabling timely corrective actions and reducing human intervention. This approach improves system reliability, minimizes resource wastage, and ensures optimal growing conditions. Furthermore, the integration of IoT supports continuous monitoring and data-driven decision-making, leading to better productivity and sustainability.The proposed system offers a cost-effective, scalable, and environmentally friendly solution, making it suitable for modern agriculture, particularly in urban and resource-limited environments.
