Low-Cost Proposal to Measure Air Quality in an Urban Area: Acapulco Case Study

The design and construction of a proposal to measure air quality in the urban area of Acapulco, Guerrero, is presented hereby, based on studies conducted on the existing pollution problems due to the growth of the metropolitan area and the lack of infrastructure to determine the current state of pollution accurately. The equipment consists of a Raspberry Picomputer system, sensors for carbon monoxide (CO), particulate matter (PM10 andPM2.5), ozone (O3) and a weather station. The Python programming language was used to construct a management and control system and then evaluate different environmental parameters. The sensors were calibrated using standard gas and statistical references.
