本工作介绍了使用环境传感器来评估室内空气质量（IAQ）结合人体生物特征。传感器阵列包括温度、相对湿度、二氧化碳和噪声监测器。该阵列被用于教室以及车辆驾驶室中，以评估封闭通风环境中个人的二氧化碳产生率。对二氧化碳产生的分析可以量化教室里一组人和车厢里一个人的平均代谢率。这些结果与使用商业代谢率仪器评估的值和流行病学研究的平均值仅相差5%。这项工作中提出的结果验证了使用被动环境传感器确定个人代谢率的可行性;这些相同的传感器能够提供IAQ的度量，有助于表征个人所在环境的安全性。
The present work introduces the use of environmental sensors to assess indoor air quality (IAQ) in combination with human biometrics. The sensor array included temperature, relative humidity, carbon dioxide, and noise monitors. The array was used in a classroom as well as in a vehicle cabin to assess the carbon dioxide production rate of individuals in a closed ventilation environment. Analysis of carbon dioxide production allowed for the quantification of the average metabolic rate of the group of individuals in the classroom, and for one individual in the vehicle cabin. These results yielded a mere5% difference from the values assessed using commercial metabolic rate instruments, and averaged values from epidemiological studies. The results presented in this work verify the feasibility of determining an individual's metabolic rate using passive environmental sensors; these same sensors are able to provide a metric of IAQ that helps characterize the safety of the environment in which the individual is present.
