The study entitled Development of Water Quality Monitoring System for Fishpond is
effective and applicable to monitor the four water quality parameters including the
dissolved oxygen, potential hydrogen, turbidity, and temperature using the long-range
wide area network. The machine can monitor the water quality approximately 2 to 3 km
wide area coverage. It is also aimed to generate dissolved oxygen to solve to unusual
amount of oxygen in fishpond. The prototype was powered by batteries. The prototype
was tested in terms of accuracy by comparing it from the water quality parameter meters.
The prototype was also tested in terms of functionality of each component whether it is
functional or not. Using this prototype, the paddle wheels generate dissolved oxygen to
solve the insufficient amount of dissolved oxygen in the fishpond. When the prototype
reaches the maximum amount of dissolved oxygen, the machine will automatically stop.
The prototype was tested between the existing water quality meters and sensors. The
percentage difference between the D.O meter and D.O sensor were 5.55%, the ph meter
and ph sensor were 20.90%, the temperature meter and temperature sensor were 13.46%.
and turbidity meter and turbidity sensor were 3.01%. The prototype was evaluated using
TUP evaluation instrument obtained an overall numeral rating of 4.58 with the
descriptive rating of “Excellent”. With a highest rating of 4.80 at “Safety” The test and
evaluation results prove that the prototype is an effective device that can be used as new
technique in monitoring the different water quality parameters.
