A large number of optical turbidimeter designs

Turbidity is an important index to evaluate water quality, and the measurement of water turbidity is of great significance to life and environmental protection. Turbidity reflects the content of suspended insoluble substances in water through the optical properties of water. Aiming at the problem of small range in existing turbidity measuring instruments, a new turbidity sensor is designed in this paper. Through the combination of scattering method and transmission method, a new measuring device structure and signal circuit processing are designed to improve the measuring range of the equipment. In addition, according to the characteristics of turbidity detection, the signal transmission circuit is designed to eliminate the influence of noise. Finally, by cooperating with the single chip computer, the measurement data is calculated and presented on the computer, and the data can be observed in real time and recorded.
