Data Collection
Data Collection came in two phases. The first part was collecting data via the means of a web
scraper. The second phase was creating a dataset from values obtained with hardware sensors.
Web Scraper Data
The first testing phase was conducted in the UCL Science Library (4th Floor). Because of
technical difficulties with counting the number of people entering and leaving the study space, it
was decided to first gather the air quality data and then correlate it with the information that is
uploaded on UCL library seating availability website. To collect all the data from the website
automatically a web scrapper coded in Python.

the values automatically. (https://www.ucl.ac.uk/library/libraries-and-study-spaces/available-study-spaces )
