The Development of Water Quality Monitoring System at Dam

Abstract

In recent years, there has been many pollution cases reported in our country and gave a huge impact to the water supply for the residential area. Lack of remote monitoring system at dams to provide alert on contamination and water level made the situation worse. To curb this problem, new remote water quality monitoring system at dams need to be developed. This project is designed to provide a reliable and rapid early detection system at dams. It is comprise of several sensors with online data and information that can be viewed at anytime and anywhere for continuous monitoring purpose. The sensors measure three water parameters which are pH level, gas presence and water level. The gathered data will be processed by a Wi-Fi module before it is uploaded to the web server and Blynk server. It can be viewed on a webpage and Blynk application through the smartphone or computer. The implementation of Blynk in this system managed to let the users stay alert with the changes that occur at the dam by sending notification on the smartphone. A pH sensor was able to detect the changes in pH of water which is required to be between 6.5 and 7.5. An ultrasonic sensor detected the dam water level. Besides that, a gas sensor that is capable of detecting the presence of smoke or gas was introduced. In a nutshell, this project managed to detect the pH level, gas presence and water level, as well as update the gathered data into the IoT platform continuously.
