A Movable Indoor Air Quality Monitoring System

Indoor air pollution has received wide attention because it harms people's health. Advantages of exiting indoor environment monitoring is detecting and improving indoor air quality. However, many obstacles must be overcome before real-time monitoring and autonomous movable system can realize, like the high cost, which lead to a low practicability in most cases. Therefore this paper provides an intelligent movable indoor environment monitoring system based on Arduino's control using various sensors to detect air quality, which has been designed to simulate users' indoor route and detect air quality real-time to help acquire indoor air condition exactly. Analyses the main factors that affect accuracy and validity of the measurement results by orthogonal experimental design, whose results show that the data acquired by the system gets high positive correlation property with data of professional equipment. The system achieves autonomous movable with low cost and results of the tests illustrate its important practical application value.
