Claim 0:
1. A control system for controlling extraction of landfill gas from a landfill via a gas extraction system, the gas extraction system comprising at least one vacuum source, well piping, and at least one well coupled to the at least one vacuum source through the well piping, the control system comprising:
a chamber coupled to the well piping and comprising at least one sensor for measuring a temperature of a landfill gas sample and one or more sensors for measuring at least one other characteristic of the landfill gas sample different from the temperature of the landfill gas sample, the landfill gas sample comprising at, least, a portion of the landfill gas being extracted from the landfill, wherein the at least one sensor for measuring the temperature of the landfill gas sample and the one or more sensors for measuring at least one other characteristic of the landfill gas sample are inside of the chamber; and
at least one controller configured to perform a method for reducing deterioration of the one or more sensors, the method comprising:
obtaining, with the at least one sensor for measuring the temperature of the landfill gas sample, a measurement of the temperature of the landfill gas sample while the landfill gas sample is in the chamber;
determining, based on the temperature of the landfill gas sample in the chamber, whether to operate the one or more sensors in the chamber to take a new measurement of the at least one other characteristic of the landfill gas sample at least in part by:
determining whether the temperature of the landfill gas sample is greater than or equal to a target temperature; and
when it is determined that the temperature of the landfill gas sample is greater than or equal to the target temperature, determining to operate the one or more sensors to take the new measurement of the at least one other characteristic of the landfill gas sample while the landfill gas sample is in the chamber;

when it, is determined to operate the one or more sensors to take the new measurement of the at least one other characteristic of the landfill gas sample, operating the one or more sensors to take the new measurement of the at least one other characteristic of the landfill gas sample while the landfill gas sample is in the chamber; and
when it is determined that the temperature of the landfill gas sample is not greater than or equal to the target temperature, operating a temperature control mechanism to adjust the temperature of the landfill gas sample.
