Implementasi Sistem Smart Aquarium Berbasis Internet of Things dengan Kendali Web dan Mobile

Aquarium maintenance requires regular monitoring of water quality and control of equipment to maintain a stable environment. Manual monitoring may lead to delays in detecting changes in water conditions and increase dependence on the owner's presence. This research aims to implement an Internet of Things (IoT) based Smart Aquarium system integrated with web and mobile platforms to support monitoring, control, and automation. The system uses an ESP32 connected to a DS18B20 temperature sensor, a pH sensor, a Total Dissolved Solids (TDS) sensor, and an ultrasonic sensor. Data is transmitted via Wi-Fi using the WebSocket protocol for real-time display. The backend was developed using Express.js with a REST API and a MySQL database, while the web interface uses React and the mobile application uses Flutter. The system provides control over actuators, including a heater, pump, and light, as well as automation for feeding, water changes, threshold settings, and automatic notifications. Testing using the Black Box Testing method covered 20 test scenarios. The results showed that all scenarios were successfully executed as expected, achieving a 100% success rate. These results indicate that the monitoring, control, and automation functions operate as intended. This system makes it easier for users to monitor and manage their aquariums while reducing dependence on manual maintenance.
