This paper describes work that has been done on 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, temperature,
pH, conductivity and the oxidation reduction potential. 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
a microcontroller-based measuring node, which processes and
analyses the data. In this design, ZigBee receiver and transmitter
modules are used for communication between the measuring
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 ZigBee to
the notification node for audio and visual display. The results
demonstrate that the system is capable of reading physiochemical
parameters, and can successfully process, transmit and display
