Prototype of a Data Logger for Monitoring Carbon Dioxide and Particulate Matter Concentrations in Juliaca

The objective of this research was to develop a prototype low-cost portable data logger that monitors real-time air quality parameters such as carbon dioxide (CO2) and particulate matter (PM10) concentrations. The data logger prototype was built based on an Arduino Nano board as central processing. It also includes a sensor module that measures carbon dioxide (CO2) concentration levels through the air quality sensor CCS811 and particulate matter concentration less than PM10 using the dust sensor GP2Y1014AU0F. Three different points in the city of Juliaca were selected according to the flow of pedestrian and vehicular traffic, such as called "Salida a Arequipa", "Salida a Lampa", and "Mercado Santa Barbara". The results obtained in the concentration of particulate matter less than PM10 in the three reference points are below the average allowed according to WHO (50 mu g/m(3)), and the results of carbon dioxide (CO2) concentration levels are less the TWA 5000 ppm in the three monitored points according to NTP 549.
