The dilemma with low-cost sensors

Low-cost air quality sensors are the talk of the town. By addressing cost issues and bringing in portability, these sensors are quickly becoming the game-changers in efforts toward better air quality. Low-cost sensors (LCS) enable dense monitoring of air pollution, allowing policymakers to target interventions at highly polluted areas, thereby improving air quality. But their large-scale use needs careful consideration, given the concerns around the accuracy and reliability of LCS data.
