Researchers at the Indian Institute of Technology Madras have developed a low-cost mobile air pollution monitoring framework.
Traditionally, ambient air quality is monitored in monitoring stations which then report air quality index (AQI). But the hitch is that the monitoring occurs only for a small geographic area.
As the levels can vary at different times of the day and setting up locations in more places is impractical, the researchers have now developed a new IoT-based mobile technology which would make it possible to map an entire city at high resolution using the low-cost devices.
