An IoT Based Manhole Monitoring System

In Mumbai, out of 3.60 lakh manholes only 1 percent follow the safety norms by BMC. Most manholes are open without any monitoring which lead to accidents or fatal accidents. Since, manual monitoring is incomplete, this leads to slow handling of problems inside the manhole and consumes more time to solve this problems. In the view of these problems we have created an Iot based manhole monitoring system which monitors the temperature, gas and the presence of lid on the manhole and along with this, transmits information to a standard authority using the WIFI module. The proposed system is low cost, low maintenance, IoT based real time which alerts the managing station about the status of the manhole when any manhole crosses its threshold values. And thus, the concern authority can take the proper action to maintain the condition of manhole. This system reduces the risk of death of people who clean the underground drainage and also benefits the public.
