TI - Microcontroller-Based Monitoring and Maintaining Device for Saltwater Aquarium AV - TK7887 Aq8 2017 U1 - . PY - 2017/// CY - . PB - . KW - academic writing N1 - ABSTRACT: Most of the people does not give attention to the needs of saltwater fishes in an aquarium that increases its rate of morality. Several factors contribute in maintaining the water system of saltwater fishes like pH level, salinity and the hot temperature which is common in the Philippines. A system that monitors these factors is already existing but it doesn’t address how to solve the problem. In addition, the solution by many fish exporters and aquarium owners are mostly done manually and separately. In response to this, the researchers created a device that monitors the pH level, salinity and temperature and automatically maintains those parameters through the use of correctors. It will also be connected to the mobile application that shows the status of the aquarium in real time so that the owners may keep track of what is happening with their aquarium anytime and anywhere. Furthermore, the owners also have the control with the light and filtration system using their mobile application. This project improved the overall monitoring and maintenance of the quality of water for saltwater fishes. It significantly reduced time, effort and money since the physical interaction was minimized; F N2 - ABSTRACT: Most of the people does not give attention to the needs of saltwater fishes in an aquarium that increases its rate of morality.
