Consciousness of Multiparameter Sensor Network

The paper contains the design of a multi-parameter data acquisition system for a Air Quality Monitoring and publish the data over internet through embedded network. Nitrogen oxides are released into the air from motor vehicle exhaust or the burning of coal, oil, diesel fuel, and natural gas, especially from electric power plants. They are also released during industrial processes such as welding, electroplating, engraving, and dynamite blasting. Nitrogen oxides are also produced by cigarette smoking. Air quality monitoring system presents a network for indoor and outdoor air quality monitoring. Each node is installed in a different room and includes tin dioxide sensor arrays connected to an acquisition system. The nodes are hardwired or wirelessly connected to a central monitoring unit. To increase the gas concentration measurement accuracy, the various gas sensor influence quantities like temperature, humidity etc. environment effects are also measured. The data of the different sensors are transmitted using the wireless transmission technique and it is published over the internet.
