Real time online sensing of illicit discharge of wastewater into lakes

Abstract

Monitoring the illicit discharge of effluent in water bodies is made easier with the present design. The water bodies are monitored using various sensors to know the illicit discharge of effluents. The water quality parameters that are detected by sensors are fed into NODE MCU micro controller for analysis and to compare the data and check with the predefined conditions. Smart sensor network has been designed in such a way that it predicts the overwhelming water quality parameters, for example, pH, temperature, turbidity and electrical conductivity. The process of monitoring the effluents is carried out by the sensors. All the sensors are connected by sensor fusion technology through which they can compare their pre-set values and give us the accurate result on water quality status. It sends the message to the user about the standards of the effluent added to the water and also alert’s the concern authority. All the process executed is saved in the Google drive of the device as a backup every day. This instrument can be placed in various locations of the lakes. The predefined values are as follows: the pH sensor will be maintained between 6-9, turbidity less than 10NTU. If the illicit discharge value exceeds these predefined parameters messages will be sent to the water maintenance department through message and the buzzer will make a sound. The GPS is enabled for anti-theft purpose.
