IoT Based Real Time Monitoring of Delhi-NCR Air Pollution Using Low Power Wide Area Network

The clean and healthy air is essential for all living beings, and air pollution can have a significant impact on human health. It is important to monitor air quality in real time to take action to reduce the pollution level in order to maintain a healthy environment. As cities become more and more congested, the level of pollution is increasing, leading to a localized human health effects such as asthma or bronchitis. Implementation of Internet of Things (IoT) based technology with harmful gas sensors can be an effective solution for continuous monitoring of air quality. By using such a technology, one can gather data on harmful pollutants and take steps to minimize their impact on human health and the environment. In this paper IoT based continuous monitoring of the air pollution level of CO and CO₂ air pollutants carried out including temperature and humidity using different sensors and a micro-controller in Delhi-NCR (National Capital Region) at Greater Noida. The LoRa (Long Range) LPWAN (Low Power Wide Area Network) was used for data communication, and ThingSpeak an IoT analytics cloud service for storing and processing the data to be displayed on the web page. The LoRa is a wireless data communication technology, which is capable to transmit data to large distances using low power transmitter. The air quality monitoring was carried out by storing sensors data in the above cloud, analyzed, and compared with the standard air quality parameters.
