LeonR&D IoT Lab: Measurements from 8 environmental sensors of a room (id-105) for 1 month (second stage)

The data is structured as a set of objects, each representing a measurement taken by the 8 sensors at a specific time. Each object has two fields: "columns" and "values".

The "columns" field is an array of strings that represent the names of the columns in the "values" array. The "values" field is an array of arrays, with each inner array representing a single measurement taken from each of the 8 sensors at a specific timestamp. Each inner array contains the mean value of each measurement taken over a 15-minute time interval.
