Smart IoT Solutions for Subsurface Gas Monitoring and Safety in Critical Infrastructures

With increasing industrialization, everyone is learning about more life-threatening casualties. The recent few years have noticed a tremendous increase in critical conditions, eventually even leading to deaths and instant deaths of workers in sewers and manholes. These death reports and environmental concerns have been increasing at an alarming rate. Sewage gas is a combination of toxic and harmful gases. It mainly houses a vast variety of oxides of Carbon, Nitrogen and Sulphur, Ammonia, Methane which results from all the industrial wastes and household residues. Due to gases being trapped in manholes for prolonged periods, they become toxic and can be fatal if the right precautions aren’t taken. Most of the time, light don’t shine on these issues, but if they aren’t handled, they could result in the occurrence of unfortunate events. Statistics show that there are numerous deaths due to gas poisoning from the toxic gases in these tunnels. Pits connecting to subterranean supply systems are critical to their maintenance because they affect communication networks, water supply networks, gas supply networks, and power networks, among other things. To deal with all these problems affected by these dangerous gases there is a smart IOT system prototype made that has been discussed in the paper. When there is a detection of a hazard gas, the users get notified with the help of actuators/sensors like buzzer, LCD screen through which they can be alerted. Although important for city operations, a hole can be one of the safest and most dangerous assets.
