The integration of Internet of Things (IoT) technologies in aquaculture enhances sustainability, efficiency, and farmer livelihoods. This study presents an IoT-based fish monitoring system using turbidity, temperature, and depth sensors connected to a cloud platform, with data accessible via mobile application. A 10-day deployment showed reliable monitoring of water quality and depth. Beyond technical benefits, the system empowers farmers, improves decision-making, and promotes sustainable aquaculture practices through digitalization. The system integrates three key sensors-DS18B20 for temperature, turbidity sensor for water clarity, and ultrasonic sensor for water depth-connected to the ESP8266 Wi-Fi module, which acts as the central controller. Data from the sensors are processed and displayed on an LCD screen, transmitted to a mobile application for remote access, and used to control a relay module. The relay operates a 12V fan, supporting water quality management. This integration ensures real-time monitoring, efficient resource use, and improved aquaculture sustainability. IoT-enabled fish monitoring strengthens aquaculture by improving resource management, reducing manual oversight, and empowering farmers with timely data, ultimately enhancing sustainability, resilience, and rural livelihoods in food production.
