Smart Sewage Sentinel

Particularly in large cities, sewage systems play an important role. Smart cities are emerging quickly, but the issues people encounter still stem from the prehistoric era. The inhalation of hazardous gases found in the manhole is a major cause of the continued deaths of sewage employees. The multivariable, nonlinear, time-varying, and random treatment process characteristics of the sewage system contribute to its instability and unpredictability. Modern developments and sophistication in planning are greatly needed in the modern environment. Hence, this project proposes a smart sewage monitoring system based on IOT for Smart City. This project is constructed on the open-source Arduino electrical platform. The system uses multiple components of a Gas sensor, ESP32 Camera, Servo motor, DC motor, Robotic gripper, Motor Driver, and a node MCU. A battery is used in this system to store the electricity generated by photovoltaic panels. A DC motor is used to convert electrical energy into mechanical motion. Additionally, it can control speed and direction. Gas sensors are installed to avoid manhole explosions by maintaining proper underground gas concentration by detecting the presence of inflammable gases. A robotic gripper is a mechanical device designed to grasp and manipulate objects. It is used to perform tasks that involve picking up, moving, and releasing objects. Servo motors offer precise control in robotics. The ESP32 camera integrates Wi-Fi, Bluetooth, and image processing. Gas sensors monitor gas purity. Blynk App alerts the IoT system of issues and updates user data on a cloud-based platform.
