- Abstract
The use of MyOpenLab as free software was proposed in this research as an alternative to manage the turbidity data acquisition system. A thermometrics turbidity sensor TSW-10 was adapted to the Arduino system, this platform was used for the data acquisition system. Communication with the PC was established through MyOpenLab. Measurements of samples with different known values of turbidity were taken to determine the voltage value equivalent to each NTU value, and then these measurements were compared with a commercial T-100 turbidity meter, duly calibrated. The following values were obtained for the applied regressions: Linear regression with R2 value of 0.9421, logarithmic and exponential regression with R2 values of 0.9511 and 0.8972, respectively. A non-parametric Wilcoxon test was applied, obtaining a value of P = 0.881, determining that there were no significant differences between the turbidity measurement prototype of this study and the T-100 commercial equipment. The creation of a turbidity data acquisition system, completely open-source, without losing reliability was demonstrated. The use of free software and hardware, reduced the costs compared to the use of licensed software and hardware, representing a viable economic option, to use as a tool in research studies.
