Subject	Biomedical Engineering; Pulmonary and Respiratory Medicine; Computer Science Applications; Signal Processing
Specific subject area	COPD Detection by using electronic nose technology
Type of data	Text files
Data gathering	Data was acquired using a wireless acquisition card coupled to the E-nose measurement chamber. Exhaled breath measurements were detected by the following sensors: SP-3, MQ-3, TGS 822, MQ-138, MQ-137, TGS 813, TGS 800, and MQ-135. Likewise, a user interface developed in Labview V14 was used to arrange the parameters in the data acquisition.
Data format	Raw data
Parameters for data collection	For the acquisition of the measurement, a protocol was developed for the collection of the breath samples of the people where the samples were taken early in the day and on fasting to avoid errors or possible misunderstanding factors.
	On the other hand, the device was conditioned with a heating system inside the sensor chamber to maintain a constant temperature and relative humidity.
Description of data collection	Data collection was obtained from 3 groups of previously selected people with COPD disease, people with smoking and healthy people.
