Internet of Things (IoT) technology is in great demand for monitoring the pollution level of a given geographical area. For correct monitoring of the pollution level, the deployment of sensors, systems, and an architectural framework is necessary. For monitoring the pollution level of an urban area, it is necessary to geographically divide the area into sub-areas like residential area, industrial area, highway area, forests, open spaces, etc. and deploy the pollution monitoring stations at various locations. For correct monitoring of pollution levels of an urban area, the deployment of sensors and systems, and their accessibility is important. This paper proposes a framework for deployment of sensors and pollution monitoring stations. It proposes to use one central master station and multiple pollution-level monitoring stations at various places and location. Every pollution monitoring station have unique ID and location address. Central master station have access of all monitoring stations for data visibility. The pollution level at particular place, region can be observed and stored with time, day, date, month, and year by the central master station.
