Smart Manhole Monitoring System

Poor manhole maintenance causes a number of serious problems. Manholes must be periodically inspected to protect public safety. Improper covering and damaged manhole lids on the road endanger lives and generate serious problems for the general public. An IoT-based manhole monitoring system is developed to overcome these problems. This suggested method continuously monitors the manhole cover and notifies the municipal corporation supervisor anytime the manhole cover position changes. It can also monitor the water overflow through the manhole cover and poisonous gases in the sewers using the Internet of Things (IoT) technology. Sometimes, water overflows through the manhole cover and the public can’t able to see the presence of the manhole cover. In this situation, indication light falls on the actual position of the manhole cover and it alerts the public. Similarly to this, the state of the manhole covers is frequently checked, and whenever an emergency situation arises, the municipal corporation provided a piece of an alert signal indicating the information on the system issue’s current location. So that it may take the necessary action.
