In today’s world, air pollution has become one of the main challenges, especially in highly populated countries such as India. As people spend most of their lives indoors, continuous measurement of pollutant concentrations both indoor and outdoor has become mandatory. The present paper describes the design and development of a cost-effective wireless system that measures the concentration of air pollutants such as O₃, PM_2.5, and TVOC in indoor and outdoor environments. The developed system also measures the global warming indicators such as temperature and humidity. It consists of accurate, low-cost sensors connected to an advanced ARM processor. The measurement was taken at four places in Visakhapatnam, India. The system’s accuracy was examined by comparing the measured information against the standard values of the Andhra Pradesh Pollution Control Board (APPCB). The designed cost-effective mobile system measures ozone, PM_2.5, temperature, and humidity with an average accuracy of ± 5.05 μg m⁻³, ± 7.86 μg m⁻³, ± 0.8 °C, and ± 2%, respectively.

在当今世界，空气污染已成为主要挑战之一，尤其是在印度等人口稠密的国家。由于人们大部分时间都在室内度过，因此必须连续测量室内和室外的污染物浓度。本文介绍了一种具有成本效益的无线系统的设计和开发，该系统可测量 O ₃、PM _{2.5等空气污染物的浓度}，以及室内和室外环境中的 TVOC。开发的系统还可以测量全球变暖指标，例如温度和湿度。它由连接到先进 ARM 处理器的精确、低成本传感器组成。测量是在印度维沙卡帕特南的四个地方进行的。通过将测量信息与安得拉邦污染控制委员会 (APPPCB) 的标准值进行比较来检查系统的准确性。所设计的具有成本效益的移动系统测量臭氧、PM _2.5、温度和湿度的平均精度分别为± 5.05 μg m ^-3、± 7.86 μg m ^-3、± 0.8 °C 和± 2%。
