The continuous degrading of the water quality on the different bodies of water all over the world has greatly affected aquaculture and the way of living for many people. This study was able to help create a device that provides pH, temperature, and turbidity by testing the quality underwater on three different depths of Samal River. A circuit board, series of sensors, 3D printed materials, and other different components were used to assemble and create a device programmed by software for the task of gathering data from underwater. The data was gathered by retrieving water samples from different depths and testing them using sensors; the gathered data is then wirelessly delivered to a mobile phone using a communication device. The gathered data from the actual test were analyzed and compared to the standards given by the Department of Environment and Natural Resources (DENR) for aquaculture applications. The computed data shows that the time of testing does not have a significant effect on the values gathered but there was on the depth of testing, it also shows that that the measurements for the pH, turbidity, and temperature are within the range of the standards set by the DENR.
