Network of Outdoor Air Purification Systems: Air Quality Measurement, Analysis and Display Systems using Mesh Network Topology

Air pollution is being addressed in many ways by countries around the world. Even though numerous different policies have been implemented to reduce the effects of pollution, it is clear that an end is not in sight. This can only be solved by a series of parallel-running solutions that work independently but achieve the desired result. The solution proposed in the paper is a widely disseminated outdoor air filtration device that fits on electrical lamp posts and filters the surrounding polluted air with high-efficiency particulate air filters an d carbon-activated filters. These devices are connected using a mesh topology, which monitors the surrounding air quality index with industry-grade sensors and uploads live data to the cloud using Message Queuing Telemetry Transport protocol. End users can view their city’s live pollution data on a dashboard and take the appropriate precautions.
