IOT based water quality monitoring using Blynk / Ahmad Danial Rahimi Rosli and Muhammad Harith Bolhi

Being a part of modern era, it is undeniable that people rely on technology to connect with each other and to even use in our daily basis. Water quality technologies are important, especially in the field of teaching, including primary and secondary teachers, lectures and people who are working with water quality. Most of them are using pH paper to indicate water quality as they are responsible for ensuring water safety and cleanliness. But this could affect the natural ecosystem as pH papers were made of raw materials found form trees such as wood cellulose, lichens and adjuncts compounds. At the same time, deforestation will cause environmental pollution including air pollution. As we know, a tree or plant absorbs carbon dioxide gas released by combustion activities, transportation, and so on. So by preserving trees and plants, we can reduce the pollution that occurs. In other words, the change in pH indicates that there are changes in water quality. Whether water quality is getting polluted or improving. Water pollution that will cause poisoning to those who drink it and that is why we need to monitor. Therefore, we have come up with an idea to make an IoT based water quality which is monitored by using Blynk application. This project aims to ease the users so they do not have to worry about the condition of nature ecosystem. We will be using Analog pH Sensor which will connect with pH Signal Conversion Board so that it can sense water quality and water pH. At the same time it will notify users whether the water is acidic or alkaline. By referring to Blynk application on a device. The Arduino IDE software will be the major part in making this project successful. We went from proposing ideas to our supervisor, to writing a report of our project and constructing the hardware for the system. The main component of this project is pH Signal Conversion Board and NodeMCU ESP8266 wifi modules, where the coding will be complied and uploaded. In conclusion, we hoped that this project will help the society in monitoring and control the water condition.
