Indoor Air Sensing: A Study in Cost, Energy, Reliability and Fidelity in Sensing

The rise in environmental pollution and degradation of air quality worldwide has dragged researchers’ attention due to its direct societal impact. Studies reveal that the indoor environment is more polluted than the outdoors. In this paper, a framework for indoor air quality monitoring has been presented. We have developed a portable and cost-effective air quality monitoring device. The device generates fine-grained data for a combination of different pollutants and meteorological sensors (humidity and temperature). In this work, an energy-aware Environment Monitoring Device (EMD) has been developed with an adaptive sampling rate. Different aspects of the EMD have been presented with an analysis of their power consumption. The proposed technique has reduced more than 45
