Ambient CO₂ time-series data for a typical academic office

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.
