Measuring air pollutant standard index (ISPU) with photonics crystal sensor based on wireless sensor network (WSN)

Information systems of air pollutant standard index (ISPU) with photonics crystal sensor which consist of three primary section viz. station as sensor acquisition of air pollutant, server as collecting and data logging, and graphical user interface (GUI) as user facilitating while data acessed has been built. Each station is equipped with five sensors, each of which serves to read the CO gas, SO₂, NO₂, surface ozone (O₃), and dust particles (PM10)^[1]. To optimize the performance of the system to be able to retrieve data from areas that are difficult to reach, then the data transmission from the station to the server using wireless communication. Transmitted data is then stored on the server. The saved data can be displayed either in the form of desktop and web applications in realtime and non-realtime.
