Kablosuz algılayıcı ağlar ile hava kirliliği ölçüm ve görüntüleme sistemi uygulaması

Today?s communication technologies have been triggered by consistently increasing population, developing life area and the need for information. The place of the communication of yesterday as being cabled is now becoming wireless. Wireless network technologies have been progressed via wireless communication. Wireless network technologies that were used first by military purposes because of high cost are now started to be used in many fields towards the needs of human beings and the decrease in cost. The reasons of using this technology are being more suitable to natural conditions than the cabled one, its reliability, its flexible structure, producing a solution with low cost, self organization, using its energy balanced inside the network and providing easy establishment. The purpose of wireless sensor networks is to provide easy access to data at any moment. It performs this by collecting data, processing, analyzing and disseminating it. In this thesis, air contamination measurement and visualization system with WSN is developed and applied. Sensors which are programmed to quantify the density of Methane (CH4), carbon monoxide (CO), isobutene (C4H10), ethanol (CH3CH2OH) and hydrogen (H2) gases are placed into the planned regions in Duzce University Konuralp Campus and the density of each gas in every region has been taken. Air contamination is determined by these gas density values. Data taken by sensors has been transferred to MySql database, and then it is transferred to the visualization interface that is prepared by PHP web programming language. Air contamination changes are shown instantly on a map given in the web interface.
