Development of an loT Web-Based Water Temperature Control System for Nano Fish Tanks

Nano fish tanks are highly sensitive to temperature fluctuations due to their small water volume, presenting risks to aquatic life. This paper introduces an innovative loT Web-Based Water Temperature Control System that integrates the ESP-32 microcontroller for dynamic temperature regulation with a user-centric web application. The hardware setup, involving temperature sensors and temperature control mechanisms, interacts with a serverless software architecture to maintain ideal aquatic conditions. The system offers real-time data from sensors and interactive controls similar to the Nano tank's physical interface, powered by a cloud-based database and RESTful APIs for robust data management. The LINE Notify API enhances the system by promptly alerting users to temperature anomalies, ensuring the hardware-software integration achieves precise environmental control. Successfully tested in real-world environments, this system provides users with remote access and immediate tank status updates, offering potential for scalability in aquatic care.
