A)
IIT Bombay
B)
IIT Kanpur
C)
IIT Madras
D)
IIT Kharagpur

Correct Answer :   IIT Madras


The Indian Institute of Technology Madras (IIT Madras) researchers have recently developed a low-cost mobile air pollution monitoring framework in which, pollution sensors mounted on public vehicles can dynamically monitor the air quality of an extended area at high spatial and temporal resolution.

Traditionally, ambient air quality is measured in monitoring stations and reported by the ‘Air Quality Index’ (AQI). Since these stations are at fixed locations, they only measure the air quality of a small geographic area.

Air pollution, however, is dynamic with locations just a few hundred meters away from each other exhibiting different levels of pollution. Levels can also vary at different times of the day. However, setting up more stations is not practical because of the high costs.

Towards tackling this issue, IIT Madras researchers have developed a new IoT-based mobile air pollution monitoring technology wherein low-cost air quality sensors are mounted on vehicles to gather spatiotemporal air quality data.

For the cost of a single reference monitoring station, it would be possible to map an entire city at high resolution using these low-cost mobile monitoring devices..
