Manhole Detection and Monitoring System Using Internet of Things

The project is used to constantly monitor manholes, which serve as access points for drainage professionals to inspect infrastructure and perform necessary repairs and cleaning. Manholes play an important function in our environment and contribute to a good city. Our core system is designed to monitor the status of the manhole lid, the temperature within the manhole, the water level, and to detect the production of dangerous gases for correct management. Arduino is a micro controller board that uses the ATmega328p microchip. The Arduino has a set of digital input and output pins that can be used to connect to different expansion boards and circuits. Temperature sensors are used to monitor any temperature increases caused by power lines installed underground. Gas sensors are used to prevent manhole explosions by monitoring the quantity of subsurface gases and detecting the presence of combustible gases. Ultrasonic sensors beneath the cover employ a threshold value to detect changes in water level. Tilt sensor used to signal the tilt of the cover is open. With the help of the Ethernet W5100 module, all of the above data is delivered to the authorities (server) automatically and without any human intervention. The technology used for this design is IOT, HTML (HYPERTEXT MAKEUP LANGUAGE) and WEB SOCKET protocol (used for full-duplex real time communication between web server and its clients).This makes it easier to establish multiple manhole monitoring systems and leads to an error free transmission of the information.
