1. A system for controlling extraction of landfill gas from a landfill, the system comprising:
a plurality of in situ control mechanisms, each of the plurality of in situ control mechanisms comprising:
a gas analyzer; and
an actuator communicatively coupled to at least one flow control mechanism configured to control flow of landfill gas being extracted from at least one well of the landfill; and
a device manager communicatively coupled to the plurality of in situ control mechanisms using a star network of wireless data links, wherein:
the plurality of in situ control mechanisms are configured to communicate to the device manager via the star network of wireless data links, data comprising sensor measurements obtained by the plurality of in situ control mechanisms;
the device manager is configured to communicate to the plurality of in situ control mechanisms via the star network of wireless data links, commands instructing the plurality of in situ control mechanisms to adjust flow rates of landfill gas being extracted from the landfill, the commands being determined based on the data communicated by the plurality of in situ control mechanisms; and
the plurality of in situ control mechanisms are configured to control respective flow control mechanisms to adjust the flow rates of the landfill gas being extracted from the landfill responsive to the commands communicated by the device manager.
