Policy Brief: Low-Cost Real-Time Sensors for Air Quality Monitoring – Indore


Human health depends on clean air. When air is polluted with fine particulate matter (PM2.5), black carbon, or other aerosolized pollutants, our health suffers. Air pollution is linked to over 3 million deaths each year, and nearly all inhabitants of the world’s largest cities are exposed to air pollution levels that are above the healthy limits (Lim et al. 2012). In addition, while air pollution affects everyone equally, it does not affect everyone equitably.

This policy brief is intended for Smart City officials, health planners, and environmental health offices. It contains information on low-cost air quality sensors (AQSs), including: how low-cost, commercially available AQSs differ from traditional air quality monitors, benefits of using low-cost AQSs for municipal monitoring, limitations of low-cost AQSs, comparison of various low-cost AQSs, and recommendations for purchasing low-cost AQSs that will work best in the three Building Healthy Cities partner cities. JSI/Building Healthy Cities. 2019.
