DESIGN OF TURBIDITY MEASUREMENT INSTRUMENT BASED ON NIR LED

The quality of water is essential to human beings, aquaculture and industry production. It is important to monitor several parameters of water and turbidity is one of them. The scattering, transmission and scattering- transmission synthesis method can be used for turbidity measurement. All these methods are the use of characteristics of light, according to the scattering or transmission of light degree to determine the degree of turbid water. In this paper, we discussed the hardware, software and algorithm of turbidity measurement based on NIR LEDs.
