The Design of an embedded Self-Diagnostic Hybrid Aquarium Control System

摘要

An aquarium control system which permits the monitoring and management of most of the parameters of the electrical devices that can be found in an aquarium has been designed in the course of this project. The microcontroller used to realize it combines a real time clock and a temperature sensor in order to control the seven relays used for switching of the various aquarium resources. The liquid crystal display shows the current-date and time, the temperature, water level and light level as detected by the sensors. Also, it permits one to visualize each port status. Other important features include an automated mechanical feeding device for the aquarium as well as automated water draining and refilling operations of the aquarium after a specific time frame. This system offers flexibility in the control of operations by providing a user interface with which parameters can easily be adjusted. The flexibility that exists in the system makes room for future enhancement.
