The article is devoted to the introduction of the Arduino Uno microprocessor assembly as a cheap and more affordable analog of the National Instruments USB-6009 data acquisition device in the development of a laser measuring system for the measurement of fluid turbidity. This system is based on fixing the transmission and scattering of light by means of photosensors — turbidimetric and nephelometric. Also, the ambient temperature and the sample of the liquid are taken into account, therefore, the system has thermal sensors. The developed measuring system uses signals obtained from potentiometers (imitators of photodetectors) as sensor signals. Such a construction allows to debug and compare the two solutions with absolutely equal conditions by adding the optoelectronic part, without significant complication. The hardware and software solution for working with these platforms is presented in the LabVIEW programming environment and a structural-functional diagram is shown.
