Data Set For: Raw Data Collected From NO2, O3 And NO Air Pollution Electrochemical Low-Cost Sensors

This data set contains data from two Captor nodes. These are prototypes nodes that were developed at the Universitat Politècnica de Catalunya (UPC) in order to study the effects of the sensor data gathering process on the use of low-cost sensors for air quality monitoring. Specifically, the captors nodes have tropospheric ozone, nitrogen dioxide, and nitrogen monoxide electrochemical sensors. They also have a temperature and relative humidity sensor inside the box. 
Two Captor nodes were placed in a reference station in Barcelona (Spain) for four months (January 2021 to May 2021), at a sampling frequency of 0.5 Hz. The data set contains a "readme" file with a brief description of the five files that make up the data set.
