The Mobile Air Quality Analysis Machine is an innovative device designed for monitoring air pollutants in various indoor and outdoor environments. Poor air quality likely led to lung diseases like asthma, COPD, and lung cancer. However, indoor air quality is currently expensive to evaluate, and at least 440,000 workers were suffering from poor health conditions due to dangerous levels of air pollution in their workplaces. Therefore, creating an economical, efficient, and effective device that could evaluate indoor and outdoor air quality is crucial. At the same time, its real-time monitoring capabilities can help protect workers and prevent health problems. Equipped with several sensors to detect air pollutants and collect samples of condensate water from the air, the machine provides a more accurate measurement of air quality. Its mobility derives from four motors, allowing for more comprehensive data collection and analysis, as the machine can cover a wider area. After collecting data from 4 typical environments, a relation of the pH value of the condensate water and air’s polluted gas concentration was generalized. Furthermore, the device provides real-time data analysis and visualization through 0.96 OLED, allowing for immediate detection of air pollution and facilitating effective and timely responses. The device can be implemented in indoor environments such as factories and warehouses, alerting workers to hazardous pollution indoors. The machine is a promising solution to the challenges of air pollution monitoring, and its potential applications are vast. This paper discusses the design, development, and testing of the machine.
