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:

DATE,CO2

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 co2meter.com. More details here: https://www.co2meter.com/blogs/news/6010192-how-does-an-ndir-co2-sensor-work

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