Note on Duplication Levels
======================================================================
While the code in this file seems very duplicated, it is just the
result of using SQL-Alchemy (ORM) and the repetitive nature of the
project as a whole. At the time of writing, the expected amount of
light meters is three and each one must take their own readings.
But, they must keep their readings separate from each other. This
means a table in the database for each meter. This is the main cause
for the repetitive/duplicated code.
Because this project has fixed requirements, the hard-coded nature is
a trade-off because of this. If the project increases the amount of
light meters it uses, this will probably need to be refactored.
