| dc.description.abstract | An automated dissolved oxygen controller is an instrument used to measure the dissolved oxygen in a tank and releases a certain amount oxygen from the aerator using the data measured. Maintaining and monitoring the right amount of oxygen in fish tank is hard to achieve. Checking the dissolved oxygen from time to time is very laborious and time consuming. The objective of this study was to fabricate a locally dissolved oxygen meter with Arduino microcontroller and aerator. It also aimed to evaluate the automated dissolved oxygen and determine the cost of the system. It is envisioned by this study to automatically measure and monitor the dissolved oxygen and supply the oxygen needed by the fish in tank digitally to avoid over aeration. The study was conducted from March 2019 to April 2019 at the Land and Water Field Laboratory, Engineering Farm, College of Engineering, Central Luzon State University, Science City of Muñoz, Nueva Ecija. The system composed of the Arduino microcontroller, dissolved oxygen sensor and aerator. The study uses the dissolved oxygen solution to calibrate the sensor. Calibration was monitor using the Arduino Program Application. The controller was set to operate the aerator when DO is below 4ppm and stop when it reaches 9ppm. The normalized Root Mean Sqaure Error (nRMSE) was used for evaluation to get the acceptable range of dissolved oxygen measurement when the aerator turns on and off. The result of the evaluation shows that the range from 3.90ppm to 4.00ppm is acceptable when turning on and 9.00ppm to 9.10 is acceptable for turning off the aerator. The system costs Php 19,531. | |
