Low-cost Particulate Matter (PM) sensors offer an excellent opportunity to improve our knowledge about this type of pollution. Their size and cost, which support multi-node network deployment, along with their temporal resolution, enable them to report fine spatio-temporal resolution for a given area. These sensors have known issues across performance metrics.

- - Airborne particulate matter (PM) poses significant health risks, causing nearly 9 million premature deaths annually, particularly affecting respiratory and cardiovascular health.
- - Low-cost optical sensors for PM measurement are being explored for personal exposure monitoring, although their accuracy can be influenced by environmental factors like humidity and temperature, as well as different pollution sources.
- - A study tested 40 individual low-cost optical PM sensors against high-grade instruments, revealing varied performance, especially in detecting pollution spikes; a combination of different models could enhance monitoring effectiveness and pollution source tracking.
