Nowadays, water leakage has become one of the major issues in the water distribution system, and it can cause a lot of water loss through water pipelines. Hence, causing financial loss if it goes undetected at an early stage. In this project, we present the principle of real-time monitoring water leakage systems via the Internet of Things (IoT). IoT is an important component of smart tracking and real time monitoring, which connects people and systems through wireless technologies. The device used to analyse the water leakage in the pipeline is the water flow sensor. The water flow sensor is utilised in this research to measure the water flow rate in the pipeline in order to solve all water-related issues such as leakage and usage. The system focuses on standard housing pipes, and the collected data is displayed through a smartphone. In addition, a newly developed fully integrated water leakage system had been designed and built. The result shows that the system is fully function and provide high accuracy and stability of water flow rate with 98% of accuracy. The system is also capable of transferring real-time data to smartphones via the Blynk application and alert the users when leaks are detected, and the reading is more than the lower and upper limit of the threshold data.
