AIR CONTAMINATION MEASUREMENT AND VISUALIZIATION APPLICATION WITH WIRELESS SENSOR NETWORKS

22nd IEEE Signal Processing and Communications Applications Conference (SIU) -- APR 23-25, 2014 -- Karadeniz Teknik Univ, Trabzon, TURKEYWOS: 000356351400056The reasons of using Wireless Sensor Networks (WSN) 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 signal at any moment. It performs this by collecting data, processing, analyzing and disseminating it. In this study, 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 (H-2) 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.IEEE, Karadeniz Tech Univ, Dept Comp Engn & Elect & Elect Eng
