Multiparameter Web Sensor

Design a multi-parameter data acquisition system for an Air Quality Monitoring and publish the data over internet through embedded web server The most common causes of CO exposure are fires, faulty combustion heating systems, exhaust from internal combustion engines and heating gases other than natural gas. Leading cause of accidental poisoning deaths is due to carbon monoxide. CO impairs oxygen delivery and has its most lethal effects on organs requiring high levels of oxygen like the brain and heart. 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, two gas sensor influence quantities like temperature and humidity are also measured. Therefore, the proposed work is multi parameter data acquisition system for air quality monitoring and to publish the data over internet through embedded web server. The data of the different sensors are transmitted using the wireless transmission technique and it is published over the internet.
