Implementation of Indoor VOC Air Pollution Monitoring System with Sensor Network

The air quality monitoring has become one of the most important and critical issues as human beings are paying more and more attention to the living quality. Various countries legislate on air quality norm related to the monitoring and measurement standards of air condition. However, most of monitoring stations for air pollution are set up in outdoor and monitor sources of air pollution and global warming gases in big region, neglecting the importance of Indoor Air Quality (IAQ). In this paper, we implement a Total Volatile Organic Compounds (VOCs) air pollution monitoring system to report value of VOC's concentration in indoor environment. The air pollution monitoring system is with long term monitor and sets up indoor gases Wireless Sensor network (WSN) with the consideration of the cost, development complexity, and the operation convenience. Through experiments and evaluation in the indoor painting environment, we have verified the feasibility of the system and shown the variation of indoor air quality.
