Turbidity of water refers to the content of suspended particles which are composed by large number of bacteria and pathogens. In aquaculture, the aquatic animals are influenced by the particulate matter concentration. It is necessary to monitor the turbidity. The measurement results of traditional turbidity detectors are easily influenced by environmental light, chromaticity, temperature factors. In order to solve the problems mentioned above, the intelligent optical fiber turbidity sensor was designed and developed based on IEEE1451.2 communication protocol. The sensor was composed of photoelectric detection module, signal transmission module and intelligent processing module. In the photoelectric detection module, a 880nm infrared light emitting diode was applied as the light source, and the scattered light was measured at vertical direction which could effectively reduce the influence of chroma. In the signal transmission module,the collected scattered light current signal was processed to obtain a linear DC voltage signalwith a linear relationship by the proportional circuit, I/V conversion, filtering and detecting circuit. In order to reduce the temperature influence and improve the detecting accuracy of the sensor, an intelligent processing module was designed based on IEEE1451.2 communication protocol. The temperature compensation algorithm was proposed and the TEDS parameter was calibrated to coducte the temperature compensation of the turbidity sensor. The performance of the sensor was tested. The experimental results showed that the accuracy of the sensor was within ±1.5%, the stability error was within ±1.0%, which satisfied the requirement of aquaculture turbidity measurement.
