This paper presents the design and implementation of a portable air quality monitoring device optimized for real-time data collection and transmission. Centered around the ESP32S3 micro-controller for its robust Wi-Fi capability, the device integrates two key sensor modules: the M701SC for measuring temperature, humidity, PM10, and PM2.5, and the SEN0377 for measuring CO and NO2 concentrations. To enhance its functionality, a NEO-7N module is employed for GPS-based location tracking, while an SD card module allows for onboard data logging. The device is powered by eight 21700 battery cells, ensuring continuous 24-h operation, including data acquisition and streaming. The enclosure, designed with aesthetics and durability, is 3D printed using PETG material. Temporal and spatial air quality data collected from various locations in the Phu My Hung area of Ho Chi Minh City demonstrate the device’s effectiveness in real-world applications. Thiswork underscores the potential of integrating advanced electronics and industrial design to create efficient environmental monitoring solutions.

摘要

This paper presents the design and implementation of a portable air quality monitoring device optimized for real-time data collection and transmission. Centered around the ESP32S3 micro-controller for its robust Wi-Fi capability, the device integrates two key sensor modules: the M701SC for measuring temperature, humidity, PM10, and PM2.5, and the SEN0377 for measuring CO and NO2 concentrations. To enhance its functionality, a NEO-7N module is employed for GPS-based location tracking, while an SD card module allows for onboard data logging. The device is powered by eight 21700 battery cells, ensuring continuous 24-h operation, including data acquisition and streaming. The enclosure, designed with aesthetics and durability, is 3D printed using PETG material. Temporal and spatial air quality data collected from various locations in the Phu My Hung area of Ho Chi Minh City demonstrate the device’s effectiveness in real-world applications.
