研究目的
To analyze air quality by measuring PM10 variables and polluting gases in the air, and to develop a low-cost device for this purpose.
研究成果
The developed low-cost system provides close approximations to real air quality values, confirming high PM10 levels in measured areas like Ventanilla. It helps monitor pollution for preventive health measures, especially for outdoor workers, and highlights the need for traffic control and environmental management in Lima.
研究不足
The calibration of sensors is complex and requires mathematical calculations for accuracy; the system has a margin of error and may not fully match professional equipment. Future work includes storing historical data and improving scope.
1：Experimental Design and Method Selection:
The system uses an Arduino-based architecture with low-cost sensors to measure air quality parameters. It involves designing a matrix of sensors, calibrating them using datasheet data, and processing data with an ATmega328p microcontroller.
2：Sample Selection and Data Sources:
Measurements were taken in specific locations in Lima, Peru (Ventanilla and Los Olivos districts), both indoors and outdoors, over 1-hour periods.
3：List of Experimental Equipment and Materials:
Sensors include DTH11 (temperature and humidity), MQ135 (pollutant gases), MQ07 (carbon monoxide), DSM501 (PM10 particulate matter), an Arduino microcontroller, and a 20x4 LCD display.
4：Experimental Procedures and Operational Workflow:
The system was exposed to open air for 3 hours; sensors measured analog signals, processed by Arduino, and displayed on LCD in real time.
5：Data Analysis Methods:
Data were compared with standards from DIGESA and SENHAMI, using calibration based on sensor datasheets.
