The CGM6812-B00 module is CH4, H2, LP and other combustible gas detection modules based on TGS6812-D00 sensors. The TGS6812 adopts the principle of catalytic combustion and can detect 0-100% LEL(H2, CH4, propane, butane, etc.); The CGM6812 module has an analog linear output proportional to the gas concentration and adopts moisture-proof coating, which can be safely used in environments requiring waterproof and insulation. It is the choice for leakage detection of combustible gases such as hydrogen.
