Abstract
A method and apparatus for the detection of methane gas including a low-cost low-power infrared methane sensor integrated with a smart energy network endpoint node, a volume corrector, or an electronic data recorder for transmission of alarm conditions and detector data between the instrument and a remote gas utility company. An independent gas calibration/verification cell may be included in the methane detector for periodically testing the functioning and calibration of the infrared sensor. An infrared carbon monoxide sensor and associated calibration/verification cell may also be installed with the methane sensor.
