Technology advancement, industrialisation, and globalisation have been significant reasons for air pollution outdoors and indoors. It may surprise us that we spend about 80% of our time indoors breathing toxic, stale, polluted air, making us sluggish and fretful. In contrast to outdoor air, indoor air does not recycle consistently. It traps and builds pollutants from wood and coal stoves, furniture and building materials, paints and solvents, cigarette smoke, and cleaning supplies. The prolonged exposure to these hidden pollutants can prompt respiratory disorders such as lung disease, pneumonitis, asthma, pulmonary hypertension, and chronic obstructive pulmonary disease (COPD). It is enduring and is not curable, which has been a threat to humanity for ages. COPD's major cause is airborne particulate matter and other toxic compounds emitted from indoor and outdoor sources. Outdoor air pollution can be controlled only by acquiring changes in the vast population, wherein for indoor, every individual may create a major impact on improving air purity, thereby promoting health. The proposed design model for monitoring indoor air quality was tested in a normal and stimulating environment where we live. Parameters tested included temperature, humidity, amount of PM2.5, and the concentration of CO, CO, and NH. These parameters were monitored for five to 6 h per day for 8 days. Results indicate that the total air quality lies in the moderate range. Further study will be helpful to utilise this module as an effective Indoor air quality (IAQ) monitoring system. HIGHLIGHTS: • A simple, effective, inexpensive integrated gas sensor module (IGSM) has been proposed in this study to monitor the indoor air quality index (IAQI). • Indoor air quality was tested in a normal and stimulating environment for 8 days. • The integrated gas sensor module (IGSM) was composed of sensors in series, and the outputs for the respective parameter were measured easily. • Among the parameters tested, CO and PM2.5 lie in the moderate range, while other pollutants within the normal range reveal that the tested air quality is moderate.
技术进步、工业化和全球化是造成室外和室内空气污染的重要原因。我们可能会感到惊讶，因为我们大约 80%的时间都在室内呼吸着有毒、陈旧、污染的空气，这使我们变得迟钝和烦躁。与室外空气不同，室内空气不会持续循环。它会捕获并积累来自柴火炉、家具和建筑材料、油漆和溶剂、香烟烟雾和清洁用品的污染物。长时间暴露在这些隐藏的污染物中会导致呼吸道疾病，如肺病、肺炎、哮喘、肺动脉高压和慢性阻塞性肺疾病（COPD）。它是持久的，而且无法治愈，这对人类来说已经是一个长期的威胁。COPD 的主要原因是室内和室外来源排放的空气传播颗粒物和其他有毒化合物。只有通过改变庞大的人口数量才能控制室外空气污染，而对于室内空气，每个人都可以对改善空气纯度产生重大影响，从而促进健康。在我们生活的正常和刺激环境中，对监测室内空气质量的建议设计模型进行了测试。测试的参数包括温度、湿度、PM2.5 量以及 CO、CO 和 NH 的浓度。每天监测这些参数 5 到 6 小时，共监测 8 天。结果表明，总空气质量处于中等范围。进一步的研究将有助于利用该模块作为有效的室内空气质量（IAQ）监测系统。要点：• 本研究提出了一种简单、有效、廉价的集成气体传感器模块（IGSM），用于监测室内空气质量指数（IAQI）。• 在正常和刺激环境中对室内空气质量进行了 8 天的测试。• 集成气体传感器模块（IGSM）由串联传感器组成，很容易测量各个参数的输出。• 在测试的参数中，CO 和 PM2.5 处于中等范围，而其他污染物处于正常范围，表明测试空气质量处于中等水平。
