DS 05

This dataset includes responses from a gas multi-sensor device deployed in an Italian city from 2004 to April 2005. Hourly response averages and gas concentration references from a certified analyser were recorded. For the experiments involving the creation of new records, the data from 2004 was used as the Primary Source, and measurements from 2005 were treated as the new records. These dataset variables do not present any increasing or descending trend but show a daily seasonal component and higher noise levels than the other datasets.
