Small Single Board Computers based Smart Manhole Monitoring and Detection System

Accidents now frequently culminate from missing or broken maintenance manhole covers. In developing countries, maintenance holes receive insufficient care. Both fatalities and serious injuries may result from incidents of this nature. This research study provides a solution to this problem. Several sensors are coordinated to screen the sewage vent cap and prevent similar incidents thoroughly. This recommended solution includes a gas cover to keep track of the gas’s toxicity that the sewage systems discharge. A tilt sensor also shows whether the maintenance hole may tilt. A float sensor also alerts individuals when the water level rises too high. If any parameters cause an alert, they SMS a selected municipal corporation mobile number and upload it on the IOT website. Also, all parameters are regularly updated on the webpage. The suggested real-time, cost-effective, and low-maintenance IoT system is a maintenance hole that alerts the management station when it exceeds specific threshold values. Not only does this technology help the general population, but it also reduces the death risk for people who manually clean underground drainage.
