Abstract
A differential monitoring system of carbon dioxide levels within an associated building with a monitoring zone including a quantity of captured carbon dioxide and a reference zone that is spaced away from the monitoring zone. The differential monitoring system includes a first carbon dioxide monitoring inlet disposed within the monitoring zone. A second carbon dioxide monitoring inlet is disposed within the monitoring zone in spaced relation to the first carbon dioxide monitoring inlet and/or is disposed within the reference zone in spaced relation to the first carbon dioxide monitoring zone. A controller is operable to determine when a carbon dioxide level at the second carbon dioxide monitoring inlet exceeds a carbon dioxide level at the first carbon dioxide monitoring inlet by a predetermined differential threshold. The inlets can be part of an aspirated sampling system and/or part of a distributed sensor system. Methods of monitoring carbon dioxide levels are also included.
