Data analysis of Air Quality: A Study of Low-Cost Sensors in Heilbronn, Germany
Air pollution is one of the most critical global environmental issues, with significant impacts on human health and ecosystems. Each year, millions of deaths are recorded due to poor air quality, along with high economic costs related to the treatment of pollution-induced diseases. While professiona...

| description |
Air pollution is one of the most critical global environmental issues, with significant impacts on human health and ecosystems. Each year, millions of deaths are recorded due to poor air quality, along with high economic costs related to the treatment of pollution-induced diseases. While professional air quality monitoring stations are effective, their high cost limits their deployment in many areas. In response, low-cost sensors have emerged, which, although affordable, face challenges regarding accuracy and calibration. This study focuses on the analysis of data collected over five and half weeks by three low-cost sensors at the LUBW Station Heilbronn, aiming to compare the results with the reference data from the station. The findings will help identify the most suitable calibration methods to improve the quality of the information provided by these sensors. |
