The project team has identified the issues of natural disasters and water pollution resulting from negligence and exploitation by water users for personal gain. Moreover, the discharge of untreated wastewater into rivers and canals exacerbates these problems. To address these challenges, they propose leveraging knowledge in science and technology, alongside automated systems, to develop a community water quality inspection robot. This robot will be remotely controlled using radio waves and will conduct surveys of distant or difficult-to-access water sources to monitor water quality. The system comprises hardware developed with an Arduino Uno R3 Wifi ESP8266 board and software programmed in C++, which commands sensors and various devices within the system to function accurately. It facilitates the measurement of various water parameters, including Total Dissolved Solids (TDS), pH levels, and Dissolved Oxygen (DO) content. Data is stored through Google Sheets and analyzed. This setup is adept at detecting the accumulation of pollutants that may lead to water deterioration. The accuracy of the robot's water quality measurements was validated by comparing them with water samples measured using a Vernier DOV 2-001 DO meter and a Yieryi Professional digital water quality tester (pH and TDS). The results indicate that the robot's measurements for DO ranged from 7.54 to 8.90 milligrams per liter, pH ranged from 5.08 to 5.76, and TDS ranged from 202 to 246 ppm. When compared with the Vernier DOV 2-001 DO meter and the Yieryi Professional digital water quality tester (pH and TDS), measurements for DO ranged from 7.37 to 8.73 milligrams per liter, pH ranged from 4.87 to 5.55, and TDS ranged from 184 to 228 ppm. Importantly, these measurements were consistent across all points.
