This paper proposes a more efficient water monitoring and control system for water utilities to address the current water wastage problem, utilizing IoT and Android applications. The integrated system aims to enhance real-time data collection, analysis, and remote management, empowering water utilities to optimize resource usage and mitigate environmental impact. Conventional water tanks cannot monitor or control the water level in the tank, leading to a significant amount of wastage. Implementing smart water tank systems with automated monitoring and control features can not only prevent wastage but also enhance overall water management efficiency. Ultrasonic sensors are used to measure the water level, while other parameters such as pH, TDS, and turbidity of the water should be calculated. Additionally, these sensors play a crucial role in ensuring accurate and real-time monitoring of water quality in various applications, such as industrial processes, aquaculture, and environmental monitoring. The integration of ultrasonic technology for water level measurement enhances the overall efficiency and reliability of water management systems. The calculated values from the sensors can be processed by the microcontrollers and uploaded to the internet through the Wi-Fi module (ESP 8266). Some other technologies have certain drawbacks in one way or another. The removal of these shortcomings and the provision of an efficient and economical solution have been the main focus of this paper. Through extensive research and innovation, our team has strived to overcome these limitations, paving the way for a more robust and seamless technological landscape.
