Abstract: The design and development of a water quality monitoring system, with the objective of notifying the user of the real-time water quality parameters. The system is able to measure physiochemical parameters of water quality, such as flow, pH, TDS and Turbidity. These physiochemical parameters are used to detect water contaminants. The sensors which are designed from first principles and implemented with signal conditioning circuits are connected to Arduino based measuring node, which processes and analyses the data. In this design, Raspberry pi is used for communication between the measuring node and notification node. The notification node presents the reading of the sensors and outputs an audio alert when water quality parameters reach unsafe levels. Various qualification tests are run to validate each aspect of the monitoring system. The sensors are shown to work within their intended accuracy ranges. The measurement node is able to transmit data via router to the notification node for Buzzer, LED, Solenoid Valve and Web server. The results demonstrate that the system is capable of reading physiochemical parameters, and can successfully process, transmit and display the readings.
