In India most of the cities adopted the underground drainage system. It’s the duty of city Municipal Corporation to maintain the underground sewer properly. Manual scavengers are needed for cleaning and maintenance, but these peoples are not aware of poisonous gas present inside the manhole since the gas are odourless. If the sewer exposed to the hazardous gas present inside the manhole like carbon monoxide, hydrogen suphide and methane may cause serious health issues, which may leads to death. To overcome all these problems effective monitoring system is needed to detect these hazardous gases in manhole.The detecting system is incorporated with gas sensors, which senses the respective gases. When the gas level exceeds the threshold level, the proposed system will give alert through the buzzer. The message will sent to the authorized officer through IoT.
