Fluorescent oxygen sensor image was obtained by using a CMOS camera in an Android OS smartphone. The obtained image was analyzed by using I_J mobile, an image analysis software for Android OS. Difference of oxygen concentration could be detected by using a red color image obtained by this system. White LED backlight module for fluorescence probe excitation could function well also with AAA cell batteries, or button batteries. By putting an yeast immobilized membrane on the oxygen sensor film, BOD could be detected by the difference of fluorescence intensity. The present simple and low cost sensor is suitable for field monitoring in developing countries.
