Data were acquired using Dallas ds18b20 temperature sensors, Bosch Moisture Sensor BME280, turbine-type anemometer and load cell capacity of 2 kg. The datalogger used was an Arduino UNO with SD memory card write/read module. The data were recorded in the Datalogger in the . CV format and later processed in the GNU Octave software. All graphics were generated in GNU Octave and gnuplot software. Data are collected at 15-minute intervals and analyzed within the day period between 10 AM and 5 PM.


Steps to reproduce

The creation of the graphs, analysis and filter of the data are performed by the GNU Octave software, so you need to open this softawe, load the library "CoolProp.Oct" (just type and press ENTER), then load the script "plot_rodrigo. m" and make the software execute the commands. Note that GNU Octave must be configured to read/write data to the "configutation_1_data" or "configutation_2_data" folder, where is the file containing the collected data (dados.csv).
