IoT enabled Real-Time Water Quality Monitoring System for early detection of contamination

Abstract

To make sure the safe supply of drinking water to the people the quality of the water must be monitored in real time in order to achieve that IOT (Internet of Things) based real time water quality monitoring system has been developed. It has some water quality sensors which measure pH, Turbidity, Total Dissolve Solids (TDS) and Temperature of the water. The data from the sensors is sent to microcontroller like Arduino/ESP32 for processing and this processed data is transmitted to the local server or cloud for real-time data visualization on a website via Wi-Fi. In case of any deviation in water quality the officials will be notified via alert SMS or email to prevent dangerous health related problems. QR scan is also introduce for the users to get water quality status quickly. This system is be installed at computer science department of Quaid I Azam University and will further expands to other departments and it will sense any contamination in real-time and stores data in database for further processing.
