Download Microcontroller Based Self-Maintained Aquarium Using PIC16F877

ABSTRACT
The design in this project showcases the implementation of a
microcontroller based self-maintained aquarium. The aquarium, consisting of the
microcontroller, LCD display, solenoid valve, relay, float switch, fluorescent lamp,
filter, dechlorination liquid, and the LDR (Light Dependant Resistor), performed
the following functions in the feeding, lighting, filtration, water replacement and
dechlorination systems in the aquarium. Water Replacement depends on the
alkalinity or acidity of the aquarium’s water which is measured by the pH meter.
The design incorporates an energy supply that powers up the entire
system of the aquarium. The system operates with the aid of the microcontroller,
relay, solenoid valve and its sensors that help control the whole functions of the
system. The design will also benefit the aquarist by maintaining the cleanliness
of the aquarium and the feeding system of the fishes.
