v5.5.1

NOTE: This version is identical to v5.5.2

WARNING: In the v5.5.1, the library.properties file was updated too early, which caused some platforms to recognize it as a new version. However, additional changes were only included in the zip package afterward, leading to inconsistencies between the platforms and the zip file. Therefore, to avoid confusion and ensure that all users work with the same updated version, a new release has been published.

v5.5.0

Updates v5.5.0:

1) Fixed the problem with xmin, xmax, ymin, ymax, zmin, zmax settings in 4DSlope.py.

2) Added the ability to create DataReport.txt alongside EstimationReport.txt to 4DSlope.py.

3) Fixed the enter mismatch in new data added on top of each other after creating DataReport.txt and EstimationReport.txt files.

4) In all files containing the limit function in the DataScience folder, the function return has been updated to np.clip(value, minlim, maxlim).

5) Cleaned extra spaces after the last line of the files.

6) Fixed the enter mismatch in new data added on top of each other after creating DataReport.txt and EstimationReport.txt files.

7) All files in the DataScience folder have been checked.

The libraries were divided into five different subgroups in v5.0.0:

1) MQ series gas sensor library

2) TGS series gas sensor library

5) Geiger Counter library

This library was customized for MG811 gas sensor!

v5.1.5

Updates v5.1.5:

1) The R2 value in the a and b constants was increased (%99) by customizing it in different ppm ranges for CO and C2H5OH gases.

2) Added MG811_Curves.py file where regressions are calculated.

3) A new Regression folder was created.

4) The definitions of the constants calculated in MG811_Curves.py are shown in detail in MG811Datasheet.txt.

5) Fixed a conflict between readppm.py and 4DSlope.py.
