Introduction to Air Pollution

Air pollution remains one of the most critical environmental challenges faced by cities around the world. The rapid growth of industries, transportation, and urbanization has significantly contributed to the increase in harmful pollutants released into the atmosphere. These pollutants not only deteriorate air quality but also pose severe health risks to the population, including respiratory diseases, cardiovascular problems, and cancer. To combat this issue, innovative solutions are required to monitor and manage air quality effectively.

The Role of EdgeAI in Monitoring Air Pollution

EdgeAI leverages the power of artificial intelligence (AI) at the edge of the network, near the source of data generation. This approach allows for real-time data processing and decision-making, which is crucial for effective air pollution monitoring. By deploying AI algorithms directly on edge devices, such as sensors and IoT devices, EdgeAI can provide timely insights and actions without relying on constant cloud connectivity.

Key Benefits of EdgeAI for Air Pollution Monitoring

  1. Real-Time Data Processing: EdgeAI enables the immediate analysis of air quality data as it is collected, allowing for faster detection of pollution levels and quicker response times to mitigate harmful effects.
  2. Reduced Latency: By processing data at the edge, EdgeAI minimizes the delay associated with transmitting data to centralized cloud servers. This ensures that critical information is available instantly, which is essential for applications that require immediate action.
  3. Cost-Effective Solution: EdgeAI reduces the need for extensive data transmission and storage infrastructure, leading to lower operational costs. This makes it an economically viable option for widespread deployment in urban areas.
  4. Scalability: EdgeAI solutions can easily be scaled to cover large geographic areas. By deploying multiple edge devices across a city, a comprehensive air quality monitoring network can be established.
  5. Enhanced Data Privacy: Processing data locally at the edge ensures that sensitive information does not need to be transmitted to external servers, thereby enhancing data privacy and security.

How EdgeAI Works in Air Pollution Monitoring

EdgeAI-powered air pollution monitoring systems typically consist of the following components:

  • IoT Sensors: These devices are equipped with sensors to detect various air pollutants, such as particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO).
  • Edge Devices: The sensors are connected to edge devices that run AI algorithms to analyze the collected data in real-time. These devices can be strategically placed across different locations in a city to provide comprehensive coverage.
  • Communication Network: The edge devices communicate with each other and with central monitoring systems via wireless networks, enabling coordinated efforts to manage air quality.
  • Central Monitoring System: While most data processing occurs at the edge, the central system aggregates information from multiple edge devices, providing a holistic view of the city’s air quality and facilitating long-term analysis and decision-making.


Air Quality Index Development by GNT

As part of the EdgeAI project, GNT contributes to the development of the Air Quality Index (AQI), a crucial metric to quantify and communicate air quality levels. The AQI leverages data collected from a comprehensive network of sensors, providing real-time insights into pollutant concentrations. By utilizing advanced AI predictive models and lightweight machine learning solutions, the AQI system forecasts air quality trends and detects anomalies. This system not only delivers current air quality status but also offers predictive analytics, enabling early warnings and proactive measures to mitigate air pollution. GNT will develop a framework for the application of AI on time-series data that is edge-oriented. The approach will allow a decentralised processing of the data offering low latency, increased privacy and security and high scalability compared to the traditional cloud-based architecture. The integration of federated learning ensures continuous model improvement, as edge devices collaborate to refine their predictive capabilities. The edge-oriented architecture scheme will be complemented by a digital twin approach based on the deployment of local Synthetic Data Generator components on all edge units. In conclusion, the air quality index development aims to enhance urban air quality management, safeguard public health, and contribute to the European Environment Agency’s efforts in monitoring and improving air quality across cities.


EdgeAI offers a promising solution for real-time air pollution monitoring, providing numerous benefits over traditional methods. Its ability to process data locally, reduce latency, lower costs, and enhance data privacy makes it an ideal choice for cities looking to improve their air quality management systems. By leveraging EdgeAI technology, cities can take proactive measures to protect public health and create a cleaner, safer environment for their residents.
