Smart City Solutions On Drainage, Unused Well And Garbage Alerting System For Human Safety

The Pollution has increased a lot from last decade. The drainage, sewage and manholes are always flooded with wastes and slurry. This results in creation of various flammable and harmful sewer gases. The consequences of this harmful gases deals with explosion risk as well as life threatening risks for the concerned cleaners. Besides this, the safety of the people living nearby the affected area may get hampered as well. The municipal authority does not have the prior knowledge about the presence of such harmful gases in the underground environment. The cleaning action may get delayed which can give rise to certain diseases. Sometimes the lid of manhole is left open causing threats. A system is needed which can continuously monitor the harmful sewer gases as well as lid and slurry levels inside the manhole and provide alarming or alerting facility on emergency conditions. This paper presents a system that monitors the harmful sewer gases as well as slurry and lid levels continuously using certain sensor modules and NodeMCU as a system on chip. The proposed system is a IOT based system with onspot buzzer and message alerting facility. The municipal authority can continuously monitor the real time data from the associated sensors and take actions according to the necessity. The system is cost effective and does not uses any bulky or additional circuitry.
