Design and Development of Drinking Water Quality Alert System with Voice Announcement for Remote Areas

Abstract: Due to rising levels of water contamination and pollution, ensuring safe drinking water is an essential public health necessity. Traditional techniques for testing the quality of water are labor-intensive, manual, and do not yield data in real time. The development of a drinking water quality monitoring and alert system that allows for ongoing, real-time water quality parameter monitoring is presented in this project. Essential parameters like pH, turbidity, total dissolved solids (TDS), and drinking water temperature are measured by the system using a variety of sensors. These sensors are connected to a Wi-Fi-capable microcontroller, which gathers and sends sensor data to a cloud platform for processing and archiving. When anomalous conditions are found, users or relevant authorities receive immediate alerts that compare the monitored values with accepted safe drinking water limits. This system helps prevent water- borne illnesses, minimizes human labor, and guarantees prompt detection of water contamination. The suggested solution is affordable, scalable, and appropriate for applications involving rural water supplies and smart cities. By making sure that everyone, even those with low literacy levels, receives important warnings, the voice alert feature increases community awareness and response times. This device can be employed in rural and remote areas for long period since the system is made to work 24/7 with little or no human intervention. IoT makes the data to be visually represent to view live data through a dashboard or mobile applications so that authorities and residents can have water quality data with them no matter what location they are in. It logs historical water quality data, used for further analysis and management purposes.
