1. A gas monitoring and control system comprising:
a gas sampling chamber having a chamber inlet, a chamber outlet and an interior chamber;
one or more sensors disposed within the interior chamber, the sensors being operable to sense one or more characteristics of a gas from a gas source and generate one or more sensor signals representative of the one or more characteristics of the gas;
a sampling inlet valve in operable communication with an outlet of the gas source and the chamber inlet;
a sampling outlet valve in operable communication with the chamber outlet and an inlet of the gas source, the sampling inlet valve and the sampling outlet valve operable to i) allow the gas from the gas source to enter the gas sampling chamber, and ii) allow ambient air to enter the gas sampling chamber,
a pump in operable communication with the sampling inlet valve and the sampling outlet valve, the pump operable to i) cause the gas to flow through the gas sampling chamber and ii) cause ambient air to flow through the gas sampling chamber; and
a controller in operable communication with the one or more sensors, the sampling inlet valve, the sampling outlet valve and the pump, the controller operable to cause the sampling inlet valve, the sampling outlet valve and the pump to operate in different states to selectively expose the one or more sensors to the gas.
