Arduino-based Multiple Aquatic Parameter Sensor Device for Evaluating pH, Turbidity, Conductivity and Temperature

This article presents the calibration and the analysis of the data being gathered by the proposed alternative low-cost Microcontroller-based Sensor Device that is capable of measuring several parameters such as the pH level, Turbidity, Temperature, and Electrical Conductivity of water samples. The proposed device is suitable for the improvement of any application that falls under Water Quality related studies. The main goal of this article is to minimize the number of discrepancy for each parameter thus, reducing the percentage error in data gathering and providing an alternative device that is low-cost and efficient for it integrates 4 water parameters in one device. The results show that the maximum percentage error for each parameter are as follows: 2.106% for pH level, 3.723% for Conductivity, 0% for Temperature, and 3.964% for Turbidity. In conclusion, the developed prototype achieved an accurate and precise water quality measuring device that is reliable to use in any water quality applications.
