Paper Title
Ozone Concentration Measurement In The Range Of 0-200 Go3/M3 By Using Ultra Violet Light Emitting Diode At Wavelength 280 Nm

Abstract
The aim of this study is to design an ozone concentration measurement using an ultra violet light emitting diode (LED-UVOM). An ultra violet light emitting diode (UV-LED) at peak wavelength 280 nm was used as the light source of the absorption cell. The principle of measurement was based on UV absorption in Hartley-band, where Beer-Lambert’s law was utilized to calculate ozone concentration. The concepts of proposed LED-UVOM design, particularly the absorption cell configuration, were clearly explained. The results show that the proposed LED-UVOM is stable and yields high accuracy in the range of 0-200 gO3/m3. Keywords- Ozone meter, UV LED, UV absorption, Ozone measurement, Ozone sensor
