Low-cost sensors, an interesting alternative for air quality monitoring in Africa.

Abstract

In Algeria, the lack of continuous measurement of air pollution is a real problem that hinders studies, strategies and decisionmaking to fight against this phenomenon. Indeed, the pollution measurement networks installed by the public authorities in the main urban centers of the country (Rahal et al., 2014) are no longer operational. This situation in Algeria is just one example among many in developing countries where the monitoring of air quality is in a deplorable state (Kumar et al., 2019), because this monitoring is a costly policy, which requires sufficient and sustainable financial means. Furthermore, the technical skills to maintain and operate the instrumentation of measuring equipment are scarce.
