Air Pollution Measurement Platform Based on LoRa and Blockchain for Industrial IoT Applications

Air pollution poses risks such as global warming and ecosystem changes. Contaminants such as harmful gas, particulate matter and residual material generated in factories are the main causes of air pollution. Therefore, there is a need for strict control of contaminants occurring in the factory. In this paper, we propose a new platform using the Internet of Things (IoT) and blockchain to monitor the air quality without restriction of space. The proposed platform provides a service that collects data in real-time through the IoT sensor device based on LoRa (Long Range) based on the contaminant generated in the factory and transmits the encrypted data to the cloud through the transaction technology of the blockchain. Using this platform, air pollution generated in factories can be managed in real-time and data integrity can be preserved. Through this study, it is possible to measure and monitor contaminants generated in the air and use them as important data to improve and overcome environmental problems caused by air pollution.
