GS301M-D02 Infrared Methane Module It is a general infrared CH₄sensor module combining advanced optical path, precision circuit and intelligent software in light of the principle of NDIR (non-dispersive infrared absorption). It realizes the ambient temperature compensation, corrects the non-linear relationship in principle, and has a variety of output forms. The infrared methane sensor module has good selectivity and makes up for the shortcomings of traditional electrochemical sensors in the selection of high-range test range. The imported infrared light source and dual-channel sensor are adopted. With automatic temperature compensation, stable and reliable measurement results can be obtained even under harsh temperature and environmental conditions. It is widely used in gas alarm and smart home system. Compared with the traditional electrochemical sensors, it has no obvious consumption. The electrolyte on the sensor will not run out due to long-term exposure to the target gas or interference gas crossing, and the service life is long. For more details, please contact us.
