IoT Based Smart Sewage Monitoring System for Smart City

Sewer monitoring is an important aspect of maintaining cleanliness around us. Lack of sewage monitoring systems may lead to blockage of the drainage. These blockages in sewers may lead to sewer flooding and pollution. Sometimes, workers may meet with accidents as they might not be aware of the condition inside the manhole. This paper aims to measure and analyze the real time levels of sewage. In order to ensure safety of the workers working under some severe conditions. This project attempts to devise an IOT technology that shall detect the level of sewage in the tunnel while keeping track of flow rate of it. If the level exceeds beyond threshold, it shall send an alert through the blynk web app. Additionally provide the information about the flow through the blynk web app itself. To obtain the desired output ultrasonic sensor, flow sensor, nodemcu esp8266, Arduino Uno and blynk web app are used in the proposed model.
