An air quality monitoring network uses 8 high-accuracy reference stations and 200 lower-cost sensors. The lower-cost sensors are individually less precise than the reference stations. Why does the network include lower-cost sensors at all, given their lower accuracy?

Question

Accepted Answer

The 200 lower-cost sensors fill spatial gaps between the 8 reference stations, revealing how pollution varies across the city at a fraction of the cost of deploying 200 reference stations

Answer

Lower-cost sensors are required by environmental regulations as a supplement to reference stations

Answer

Lower-cost sensors are easier to connect to cloud platforms than reference-grade instruments

Answer

Lower-cost sensors consume less electricity, reducing the network’s overall carbon footprint
