Time series data for ambient atmospheric CO₂ levels in a typical academic office.

The CSV file is in UNIX format, with lines terminated with ASCII LF (0xA) character.

There are two columns per record:


the DATE is given in ISO 8601 format. Generally there are 6 decimal figures in the "seconds" place, giving precision down the microsend level, though the actual timing accuracy is only like to be around a few milliseconds.

The CO2 level is given in PPM.

The sensor is a calibrated NDIR sensor bought Commercially Off The Shelf from More details here:

The data is collected using custom Python scripts on a spare laptop.
