Development of an integrated air quality monitoring system for temperature, humidity, CO, and PM10 measurement

Abstract

This study addresses the growing need for cost-effective and straightforward air quality monitoring solutions. We present the development and testing of an integrated sensor system combining DHT11, MQ-7, and GP2Y1010AU0F sensors for measuring temperature, humidity, CO gas, and PM10 levels. Our calibration tests demonstrate a sensor accuracy exceeding 96%, with individual accuracy rates for temperature, humidity, CO, and PM10 sensors at 98.42%, 96.81%, 96.95%, and 97.75%, respectively. These findings underscore the potential of our integrated sensor design in providing reliable and affordable air quality monitoring for community use.
