Abstract

This system takes the IC

A/D and AT89C52 as key module

according to Lambert-Bill’s law and colorimetric principle

uses silicon photovoltaic cells and operational amplifier to realize photoelectric conversion.Incident light and transmitted light intensity of liquid are measured.COD of the liquid sample can be automated calculated by microcontroller.Additionally

the system still has the function of print

clock and alarm etc.And the system still offers PC communication and database management subsystem to store and analyze the result of COD measurement.
