Democratising Air Quality: An Open-source Solution to Filling Data Gaps in the Global South

The advancement of low-cost sensors has sparked a boom in air quality monitoring devices. From backpack add-ons to citizen bicycles, air quality devices are enabling citizens to get involved in monitoring local air quality.

When looking at global air quality maps, however, the data for South America and Africa remain scarce. As primarily consumer-based products, these devices remain subject to demand and supply, limiting access to local air quality and air pollution for those who need them the most. Though the number of open-source designs is growing, incomplete and non-standardised documentation renders many viable designs unusable.

In this episode, Colombia-based Engineering Physicist, MSc., Daniel Mauricio Pineda, takes us through the design of a fully documented, open-source air quality monitoring device that allows for remote data gathering and customisation.
