Installing low-cost sensors to spur improvements
Installing low-cost air quality sensors placed in high traffic locations for target populations
Over 50 cities worldwide benefit from air sensor programs: the installation of low-cost air quality sensors placed in high traffic locations for target populations, such as schools and children’s health centers. The sensors track pollution levels that can inform and mobilize behavior and policy improvements. In Lima, Peru, air sensor monitoring has improved air quality by 45% in locations that service 8,000 children.
The Impact:
- Over 50 cities worldwide have implemented air sensor programs to improve air quality.
- In London, the city deployed 100 stationary air quality sensors, mobile sensors on Google Street View cars, and wearable sensors for schoolchildren. Data from the first phase revealed high pollution at 40% of sites and unexpected hotspots in outer boroughs, showcasing the value of hyperlocal monitoring.
- In Lima, Peru, the city improved air quality by 45% in locations that service 8,000 children. Better air quality is expected to increase life expectancy by more than 11 months and reduce the risk of respiratory and cardiovascular diseases by nearly 30%.
What you can do with this idea:
- Install low-cost air quality sensors in strategic locations, such as schools and children’s health centers, to monitor pollution levels.
- Raise awareness among residents about the importance of clean air and the steps they can take to protect themselves.
- Use data collected to implement and monitor measures that reduce residents’ exposure to dangerous pollutants, creating safer spaces for them to live, work, and play.
