IoT-Based Aquaponics System for Sustainable Farming

Aquaponics integrates aquaculture and hydroponics into a closed-loop sustainable farming system.The Internet of Things (IoT) enhances this integration by providing real-time monitoring and automated control, improving efficiency, productivity, and sustainability.This paper presents the design and implementation of an IoT-based aquaponics system that monitors water quality, temperature, pH, humidity, and nutrient cycles while automating feeding and irrigation.The system utilizes Arduino and NodeMCU microcontrollers, sensors (pH, temperature, DHT11), and a cloud platform for data logging and alerting.Experimental deployment demonstrates improved water quality control, plant health, and fish survival rates with minimal manual intervention.The proposed system supports precision agriculture, reduces resource wastage, and is scalable for small-to-medium farming environments.
