An optical sensor system has been proposed for measuring the degree of parched coffee berry. The principle of the method is based on a scattering intensity of the light on parched coffee berry. The system consists of a sensor head including light source and light receiver, an amplifier, an A/D converter, a computer and a display. The results show that the optimum degree berry can be obtained when the scattering intensity is about 83% of the maximum intensity and that the scattering intensity depends only on the degree of parched coffee berry and does not depend on the wavelength of the light source.
