The main purpose of this study is to develop and design a system that monitors the pH level and temperature with dissolved oxygen control in an artificial aquatic system. The probes of the sensors in pH, D.O., and temperature were immersed inside the aquatic tank to monitor their values. Using experimental methods in testing the different sensors functionality, results show that the system was able to successfully monitor these factors. Information coming from the system, such as the pH, dissolved oxygen, and temperature readings, were then displayed to an android mobile phone the Bluetooth serial module was stored and displayed to the system software.Developed Using: Embedded: Arduino | Open-source electronic prototyping platform enabling users to create interactive electronic objects.Frontend: MIT App Inventor is a web application integrated development environment originally provided by Google and now maintained by the Massachusetts Institute of Technology.For: Thesis: Bohol Island State University-Main Campus, Bachelor of Science in Computer Engineering 2018Lead Developer: Max Angelo Perin BSCpE 5Assistant Developers: Maria Jussel Cuaton BSCpE 5, Apple Joy Rapirap BSCpE 5Authors: Max Angelo Perin BSCpE 5, Maria Jussel Cuaton BSCpE 5, Apple Joy Rapirap BSCpE 5, Engr.
