Use of wireless sensor network system based on water level, rain, conductivity, oil and turbidity sensors to monitor the storm sewerage

IET Wireless Sensor Systems, Volume 12, Issue 3-4, Page 103-121, June-August 2022., 2022
Abstract Storm sewerages are crucial infrastructures in water management. In this paper, a system was developed to detect the blockage of the sewerage and the presence of illegal spills in Storm sewerages. Different nodes with sensors measuring the water level, turbidity, conductivity, and oil presence are scattered in the sewerage.
