Design of Portable Turbidimeter Based on Cygnal Microcomputer

摘要

Based on the characteristics of turbidity measurement, we have researched upon the portable light-scattering turbidity testing device by applying C8051F020.We try to simplify the circuit structure & improve the anti-interference of the device through the collection & process of data of the photoelectrical signal, as well as the control of circuit by C8051F020.Besides, the bubble disturbance inside light pathway is eliminated by means of mechanical agitating. Therefore the measurement is stablized.
