Abstract
A target gas sensor employing a radiation source () and a radiation sensor () including a reference radiation detector (), a target radiation detector (), a temperature sensor (), a temperature controller () and a target gas detection processor (). In operation, radiation source () controls a propagation of radiation (RAD) through a gas mixture (GM) contained by an airway () to radiation sensor (). Reference radiation detector () generates a reference detection signal (RD) indicative of a detected magnitude of a reference wavelength (λ) of the radiation, and target radiation detector () generates a target detection signal (TD) indicative of a detected magnitude of a target wavelength (λ) of the radiation. Temperature sensor () senses a temperature of radiation detectors () whereby temperature controller () regulates a heating of the radiation detectors () relative to a regulated detector temperature (T). Target gas detection processor () measures the target gas concentration within the sample of the gas mixture (GM) as a function of an absorbing spectral response ratio (SRR) and a temperature compensation (TPC).
