| dc.description.abstract | The project is an IoT-based Smart Water Meter and Water Quality Monitoring
System that measures water consumption and monitors water quality in real
time with the aid of low-cost sensors. A flow-rate sensor is used to measure
water consumption while a Ph sensor and turbidity sensor are used for water
quality monitoring. The sensor data collected is then sent to a remote ThingSpeak server using a GSM device where it can be monitored by both NWSC
and its customers. The server also assesses the given data against thresholds
and provides notifications to both NWSC and its customers once the thresholds
have been exceeded. The thresholds for water quality were determined by the
National Standards for Potable water while those for consumption were determined by the average monthly water consumption. With regards to the choice
of water quality parameters, NWSC sample data collected from Kampala was
assessed using Feature selection Machine Leaning and the most dominant parameters were determined as Ph, turbidity, conductivity, color and Hardness,
out of which, Ph, and turbidity were chosen on the basis of cost and availability
of the sensors. The project has also been divided into two separate systems,
wirelessly interconnected using nrfL2401 radio transceiver modules. The two
systems include the water quality and the water consumption system. This is
because the water quality sensors need to be in contact with the water, while
this is not a requirement for the flow rate sensor. Therefore, for more convenience during setup and maintenance, these two systems can be placed at two
different suitable locations within one’s home. The project therefore provides
IoT-based method of actively monitoring both water consumption and water
quality by NWSC and its customers. It is recommended that the number of
water quality sensors are increased to improve the accuracy of the water quality
assessment. | en_US |
