摘要

The design of optical sensor systems is based on the interaction between the photons of the electromagnetic radiation and suspended particles in water. The objectives of this study area are to design and develop a dwi-detector optical sensor for measuring the concentration of total suspended solids, TSS, in polluted water samples. An algorithm which requires calibration analysis has been derived for estimating TSS concentrations. The proposed optical system uses a single light emitting diode, LED, as an emitter and two phototransistors are used as detectors. Detected radiations were measured at scattering angles of 90° and 180° between the source and the detectors. The algorithm produced a high correlation coefficient and low root mean square error value.
