Design of multi-functional intelligent fish tank control system

To address the issues of complex maintenance, limited functionality, and high costs in traditional fish tanks, this paper designs a multifunctional intelligent fish tank control system based on the STM32F103C8T6 microcomputer. The system integrates temperature sensing, ultrasonic water level monitoring, water quality detection, timed feeding, automatic water changing, and buzzer alarms, enabling intelligent management of the fish tank environment. Additionally, a user-friendly interactive interface is designed. Parameters can be viewed in real-time on an OLED display, and thresholds can be set or devices controlled remotely via buttons or a Wi-Fi module. Finally, through Keil 5 software simulation and hardware testing, functions including temperature regulation, water level control, water quality optimization, and timed feeding are stably achieved by the system, effectively reducing labor costs and resource consumption.
