Development and Implementation of Wireless Multigas Concentration Cloud System

According to the report “Global Health Risks of 2004” issued by WHO (World Health Organization) in Geneva 2009 (WHO, 2012), the mortality rate of the diseases and cause of death which results from the smoke produced by burning solid fuel is ranked tenth, occupying 3.3% of the global amounts, and the DALYs (Disability Adjusted Life Years) is ranked the ninth, occupying 2.7% of the world. Once the pollution occurred in an insufficient ventilation location, the womankind and children will be the most directly affected; therefore, we hoped to focus the measurement environment on indoor surroundings in this paper. This paper proposes a pointing at several kinds of indoor pollutants and integrating multigas sensors, which includes carbon monoxide, carbon dioxide total volatile organic compounds, and so forth. Our paper combines gas sensors with WSN (Wireless Sensor Networks) nodes; we provide users with optional monitoring subjects for constructing and also adapt ZigBee and Wi-Fi modules to get united with uploading real-time sensor messages. Moreover, for the reason of decreasing installation cost of sensors and setting up easily, this paper builds a cloud data-viewing platform additionally, enabling users to observe air quality through the cloud server everywhere. 1. Introduction Though the technology progress is in thriving and robust, human’s overexploitation results in natural disasters to happen frequently; it is an extreme threaten to our living environment, so that awareness of environmental protection is rising recently, and the environmental protection issues get much more attention; one of them is air pollution. The diseases are caused by indoor air pollution such as acute lower respiratory infections, chronic obstructive pulmonary disease, lung cancer, asthma, otitis media, nasopharyngeal cancer, and cataract and cardiovascular diseases; especially the first three items are the most in common. Acute lower respiratory infections usually occurred in young children; according to statistics, there are at least two millions of children who died for this illness every year. In the Middle East, lots of women suffered from chronic obstructive pulmonary disease because of exposing in smoke for a long time. Except for common respiratory tract diseases, there is another illness called “Sick Building Syndrome,” usually taking place in large building with air condition, but the syndrome only appears when employee stays in office, including dizziness, coughing, and dry-feeling; they will ease after leaving [1]. They are caused by exposure of the high CO2
