AirSniffer: A smartphone-based sensor system for body area climate and air quality monitoring

摘要

Poor air quality is among the top environmental public health risks and significant amount of costs and productivity losses are considered to be related to poor indoor air quality. Air quality is extremely difficult for human beings to feel or sense so that most people cannot tell whether or not air quality is bad. Meanwhile, most of the existing air quality measurement devices are designed for professionals; they are expensive and beyond the reach of average users. In this paper, we present the AirSniffer, a smart phone-based sensor system, which can be conveniently used for personal body area micro-climate monitoring. The sensor node is implemented with a popular Arduino prototyping board, a Bluetooth module, and a number of low-cost micro sensors. Overall system architecture and the detailed system design are presented in the paper. Some measurement results are also presented to demonstrate the capabilities as well as the usefulness of the system.
