Project NO2

Crowd-sourcing data to measure nitrogen dioxide levels in Bengaluru’s air

Clean Air Platform, in collaboration with Sensing Local, is launching an ambitious programme to involve the citizens of Bengaluru in an exercise to measure the levels of nitrogen dioxide (NO2) at various locations across the city.

Diffusion tubes to be used to crowd-source data

Using simple and relatively cheap equipment, participants in the programme can collect samples of air at locations of interest to them, like residential complexes, schools, hospitals, playgrounds, parks and lakes, etc. The equipment, know as diffusion tubes, are to be deployed for a period of two weeks.

Pregnant women and unborn children are disproportionately impacted by NO2, with development of foetuses being hampered. This exercise draws inspiration from a street science project in Belgium, where 20,000 participants contributed to generate 17,800 data points on NO2 levels.

This programme is inspired by a project in Antwerp, Belgium where 20,000 participants contributed to generate 17,800 data points on NO2 levels.

The participants will receive the equipment and instructions on how to collect the air sample, and Clean Air Platform and Sensing Local staff will provide any assistance required.

This programme is currently in pilot stage, and will be open for participation shortly.
