In both rural and urban regions water quality assurance measures are weak. Many research projects have been launched in recent years to develop cellular systems that monitor water quality and respond quickly to maintain acceptable drinking water regulations. Water is inextricably linked to human existence. Not only being a scarce resource but the quality of water potable to drink is also poor. Ingestion of contaminated water could cause the consumer to contract waterborne diseases such as Malaria, Typhoid, and Cholera. Currently, there are lab-based systems, remote sensing systems, and automatic systems with monitoring systems. They are, however, time-consuming, inaccurate, or expensive. To solve these issues, it is proposed an IoT-based system for monitoring water quality. The incorporation of sensors in these systems makes data collection for parameters like pH, Total Dissolved Solids, and Temperature easier. These sensors collect data by connecting to a microcontroller. The information gathered by these sensors is sent to the cloud and then shown in a smartphone application. If the water quality is below threshold, the system can transmit automatic alerts to the mobile application. As a result, there is an obvious need for a dependable and cost-effective real-time water quality monitoring system, which the proposed system successfully provides.
